Apple #707: Movie Trailers

I went to an actual movie this weekend. In the theater and everything.  It's been many moons since I did that.

I saw It Follows, if you're interested.  In spite of the many questions I had -- what exactly happened with the guys on the boat?  What was the swimming pool plan supposed to be? Are there specific rules about how the transfer of following happens, I mean, do certain things need to be achieved? If you see it, you'll know what I mean.

In spite of all those questions, I liked it.  That conclusion does not seem like it would follow my list of questions, but it does follow that since the movie was set near Detroit in a landscape I recognized, and it did cool things with setting and the sense of time, I would find it eerily familiar.  It also follows that, since I can make many puns with the title, I would like it.

Anyway.  The point of all this is that a Daily Apple question emerged prior to said watching of said movie.  The friend with whom I went to said movie --we'll call him JohnCarpenter -- said, at the conclusion of the trailers, "Wait a minute. They're called trailers, but they show them before the movie.  Shouldn't they be called previews instead?"

Good question, JohnCarpenter, says I.

  • As you might guess, trailers once upon a time were shown after the movie.
  • Let's start at the beginning.
  • Long, long ago, back in the silent-era-stone age, before you were even a flicker in your parents' eye, movies used to be shown in a continuous fashion.  You'd pay your nickel, walk in and sit down at some point in the cycle.  There was a feature film, followed by several short films, including maybe a public service message from the Army or some government entity, a bit of newsreel footage, a cartoon or two, and then the feature film would start up again.
  • People would come in and sit through the whole loop.  Instead of getting up and leaving when they got to the end of the loop, they would stay and watch it all go around again.  All for one nickel.
  • In 1913, various theaters around the country began showing a 13-episode serial movie called The Adventures of Kathlyn.  Taking advantage of the fact that a lot of people liked reading serial publications in newspapers and magazines, the release of this film corresponded with the printing of the same installment in the Chicago Tribune.

  • The idea was that you'd read the episode in the paper and then go see it acted out, or vice versa.  Or if you read it one week, you could go see the next episode in the theater the next.  Or maybe somebody who read the Tribune would tell you about what they'd just read, and then you'd go see it in the theater.  You get the idea.
  • Here's a brief description of the serial, from the New York Times
"the serial detailed the experiences of Kathlyn Hare, the pretty daughter of an explorer (Lafe McKee). Kathlyn resided in a mythical India, fighting off unwanted advances from a handsome native, Umballah (Charles Clary), when not battling an endless array of ferocious jungle fauna." She also befriends native servants and frees the enslaved peoples. Naturally.
    • Interesting sidenote: the animals used in the filming of this serialized film eventually became the first animals to reside in the then-new Los Angeles Zoo. 


Newspaper ad from the Chicago Tribune for The Adventures of Kathryn. It's hard to see at this size, but the ad includes a list of Chicago theaters showing the movie. Eventually, some 200 papers ran the serialized story, and the serialized movie was shown in theaters around the country.

  • Another innovation about all of this was that at the end of the movie episode for the week, there would a be a scene depicting one of the characters in a cliffhanger of some sort, and then a title card would be laid over the image, inviting patrons to return the following week to see what became of their favorite character.  The next week, the movie would pick up with that cliffhanger and proceed from there.
  • That little teaser at the end of the episode is generally considered to be the first trailer.
  • At about the same time, the advertising manager for Marcus Loew theaters (yup, still a big name in the movie theater business today) in New York City got an idea.  A play called Pleasure Seekers was being performed on Broadway, and he had a short little film made to promote it, including footage of the rehearsals.  This was probably the first short film advertising a production, and even though it was for a play, it's still fairly close to what we think of today as a trailer.
  • This short promo for the play was inserted among that continuous loop of short films & cartoons & newsreels. It fit in very well with all those other supplemental materials, so the theaters throughout the Loews chain started doing that, and soon other theaters did too.
  • By 1915, movie theaters were making their own short films to promote their feature-length movies.  They were pretty basic, with bits from the film spliced together, and maybe a title card at the beginning and end, maybe some text laid over the film.
  • Below is the trailer for Birth of a Nation (1915), and below that, a montage of several early movie trailers. You'll note that they are all silent movies. That Birth of a Nation trailer sure makes me want to watch it. Lincoln gets shot in it and everything. Except, oh dear, the KKK are the good guys. Boy, it's hard to see them as anything but bad guys now.







  • As movie-making evolved, incorporating sound and utilizing more complex filming and editing techniques, so too did the trailers.  One particular company, the National Screen Service or NSS, made trailers for all the film companies. Even as they used these new techniques, they tended to follow a similar format, since the trailers were all made essentially by the same guy.
  • Below is the trailer for King Kong (1933). Note the use of the text laid over the scenes from the film, which is a technique from the silent era, but also the use of voice-over specific to the trailer at the end.  That is a newer innovation.  



  • By Gone with the Wind (1939), they're still using the text overlay, but now they're interspersing the voice-over telling you how wonderful the picture is, with segments from the movie itself.



  • As trailers were becoming more advanced, movie theaters were showing more of them more often. Theaters were also moving away from running that continuous loop of one feature film and many short films throughout the day.  Now they had a few set times for the film, or maybe they were showing more than one film in the same theater, and they needed to get the audience out in between.  The trailers at the end of the film gave people the message: show's over, time to move on.
  • There is one additional suggestion for the early meaning of the word "trailer," which is a more technical one.  Lou Harris, former executive at Paramount, was quoted as saying that the piece of film that contained the trailer was spliced onto the end of the feature film.  So it really did "trail" at the end of the movie.


Back in the day, this is essentially how two pieces of film were spliced together -- with tape or glue.

  • Finding the date when theaters started showing trailers before the feature film rather than after is a little more difficult.  Many people say they began making the switch some time in the 1930s.
  • Film studios tried calling them something other than trailers -- "previews" "prevue of coming attractions" and so on.  But it was too late.  "Trailers" had stuck. 
  • A few final notes. You might call these trailers: 
  • Trailers are often made while the movie itself is still being made. Sometimes the trailer editors use the rushes -- the first prints made of a day's filming, which may or may not be kept in the final edit.  So it sometimes happens that a trailer contains footage or dialogue that isn't in the final version of the film.
    • In Casablanca's trailer, Rick says, "All right, Major, you asked for it."  But he never says that line in the film. 
    • The trailer for Terminator 2: Judgment Day contains several bits & pieces that are not in the movie -- on purpose. Director James Cameron wanted the trailers to explain how the Terminators were made, to address people's skepticism about how he could be in the sequel after he'd been destroyed in the first.
  • A lot of people say that Jaws (1975) was the first movie whose trailers were shown on TV,  but actually the practice started as early as the 1950s. Movie historian Keith Johnston says the first movie to put its trailers on TV was Born Yesterday (1950), starring William Holden and Judy Holliday.
  • But here's the trailer for Jaws anyway.  Because I want you to see how the voice-over has evolved, from telling you how great the movie is to telling you about the movie (though it still seems pretty shlocky).  It's also surprising how much of the movie it shows.



  • Moviegoers from the 1980s and 1990s will remember that nearly every single trailer started with a phrase like, "In a world . . ." or "In a time . . . " It was one guy who did the voice-overs for all those trailers.  No, it wasn't Morgan Freeman, it was a guy named Don LaFontaine.  Watch this mashup of trailers and be taken back to a time when there were still voice-overs in trailers, along with all the special effects.




Finally, I just want to point out that this entry about trailers was inspired by a movie called It Follows.  Do you follow?

Apple #706: Shampoo

I would like you to think about the word "shampoo" for a moment or two.  Say it out loud, slowly.  Sham poo.

This is the stuff we put in our hair?  To clean it?  Oh, I don't want the real poo, only the fake poo will do for me.  Who came up with this word?  Who in their right mind thought this was a good idea?  And why did we all go along with it?

A word-origins mystery in need of a Daily Apple if ever there was one.




Confidently Clean / Sham Poo.  Seems like an oxymoron, doesn't it?
(Photo from somewhere on this page: Aussie Moist Shampoo 13.5 Fl Oz (Pack of 6))


  • I blame the Brits.
  • The Oxford English Dictionary folks think that shampoo comes from the Hindi word chāmpo (sometimes it's spelled cāmpo, but the c should have a horizontal line above it, which means the c is pronounced ch).
  • This Hindi word chāmpo means "to press" as in "to massage."
  • The OED further elucidates the definition by giving an obsolete definition "as designating a part of the process of a Turkish bath."
  • Because, you know, India, Turkey, same thing.


An Ayurvedic massage today, including knotted towels soaked in a mixture of rice and warm milk. Perhaps this is similar to the original meaning of chāmpo?
(Screenshot from a video showing the entirety of the massage, which begins with a head massage. Warning: once the guy stops talking and the massage starts, it's very hypnotic. From wn.com.)


  • Reading the instances when the OED found uses of the word in its earliest appearances, it does look as though a bunch of British guys were referring to a practice that was probably massage -- and misspelling the Hindi word in a phonetic English way.
    • The first instance where they found shampoo being used was from 1762, from a text called Voyage of the East Indies (or something like that; there's a lot of abbreviation). The sentence is "Had I not seen several Chinese merchants shampooed before me, I should have been apprehensive of danger."  
      • Meaning, I suppose, that if a bunch of Chinese guys get shampooed (or chāmpo-ed) and come through it safely, then it must be safe for the British guy, too.
    • One instance in 1813 actually got the spelling closer to the Hindi: "She [a Mahratta wife] first champoes her husband and fans him to repose; she then champoes the horse."
      • Ahem.
    • This sentence, from 1829, gets very specific, and it's clear that what's meant is massage: "In the East Indies, friction with the hand, or what is called champouing, is generally practiced."
    • Or this one, from 1869, also clearly describes massage: "Shampoeing [sic] may be compared to a gentle kneading of the whole person." 
    • This, going back in time to 1823, is specific, though racially uncomfortable: "We had long ago seen negroes employed in percussion upon their Barbadean masters, by whom it is termed 'Champooing.'"
    • This one, from Jean A. Owen in a book about Hawaii, where he or she is talking about Tahiti, where some Hindi people do live: "In Tahiti, too, a traveler, on entering a house is always given a mat to lie on, and his weary limbs are shampooed whilst food is prepared for him."
      • sounds like an especially nice welcome.

(Photo from Real Ease in the UK)

  • In other instances, from memoirs of travels to the Indies or letters about trips there and things of that nature, it's not entirely clear what's happening during the ch/shampooing, if it's massage or hair-washing, or what.  
    • Dickens, from Pickwick Papers: "The other shampoo'ed Mr. Winkle with a heavy clothes-brush."
      • seems more likely that he means the massage definition.
    • Thackeray, from Vanity Fair: "Pinching the bed-curtains, poking into the feathers, shampooing the mattresses."
      • since the other two actions involve manual pressure, probably the shampooing does too, but perhaps washing could also be meant.
    • Here's an even more interesting one, from someone named Haliburton (with one el) in 1838: "So our diplomatists shampoo the English, and put 'em to sleep."


Shampooing today
(Photo from eHow)

  • But over time, by 1860, the English word came to mean only the massaging of the head & washing the hair.
    • "The patient should have . . . the hair cut and shampooed, and the whole body well cleansed with carbolic soap." (1881)
    • "Brilliant with gas, and redolent of rich perfume, are the modern shampooing salons." (1881)
  • And now, just for funsies, here's one final use of the word "shampoo," submitted without comment:
    • "the shampooed body . . . is rubbed all over with a preparation of soap confined in a bag, till he is one mass of lather." (1821)
      • oh, wait. I do have a comment. I think that's a lot like what's depicted in that video of Ayurvedic massage.  Seriously.

The next time your shampoo your hair, remember these two things:
  1. champou, not shampoo
  2. it's as much about the massage as it is about the product.  
I bet you'll enjoy washing your hair more than usual.

Apple #705: Clover

St. Patricks' Day is right around the corner. Easter with all its candy is already here, if you believe the grocery story displays. (Just what does that word "Easter" mean anyway?)  Soon we'll be seeing daffodils and forsythia sprouting everywhere.  Before you know it, Spring Fever will have set in.

All right, I'll stop with the link-bombing.  The point is, I've been doing this here Daily Apple thing for so many years, I've already covered most of the obvious subjects.  So I thought it would be a good time to talk about something small, unassuming, often overlooked.  Like clover.



Clover, four-leaved, no less.

Finding a Four-Leaf Clover

  • What are the odds of finding a four-leaf clover?  On your first try: about 10,000 to 1.  
  • Keep trying, though, because apparently the pursuit is not as difficult as it's made out to be.  Some people report finding 5, 6, or 7 four-leaf clovers in a single clover-hunting session.
  • Scientific American estimates that one four-leaf clover should be present in every 1.2 square meters' worth of clover patch.  So if you've got a roughly 1-square-meter patch of clover, you'll probably find a 4-leaf one in it.
  • But 4-leaf clovers have apparently become ho-hum.  The real prize to find now is a 5-leaf clover. 


5-leaf clover. For reals.

  • You would think this would be even more difficult, but clover-hunters report finding multiple 5-leaved clovers in a single hunting session, too.
  • Clovers with 6, 7, and 8 leaves have also been found.  People have set records finding clovers with as many as 21 and 56 leaves. 


21-leaf clover, bred & grown & found in Japan by a farmer named Shigeo Obara.  I don't know if it counts as a "find" if you bred it & grew it yourself.

  • This cloverleaf bounty probably has to do with the fact that plant cultivators have figured out how to breed clover for the recessive gene that produces multi-leaved clovers.
  • Some tips for looking for the multi-leaf clovers: don't go scrutinizing each one with a magnifying glass.  Instead, find a patch of clover, preferably white clover, and cast your gaze slowly over the patch, maybe ruffling the patch gently with your hand, while you look for the shape of 4 leaves -- or 5, or anyway an odd shape that stands out from the rest.  
  • Once you've found one, keep looking in that same patch of clover because you'll probably find another one nearby.  It'll have more brothers & sisters around somewhere.

  • Speaking of cloverleaf, anybody remember the Cloverleaf in Ann Arbor, before it was downtown, when it used to be out by that Kroger?  Ah, the old days.


The Cloverleaf today.  Look, it's all downtown and cafe-like and everything. Right on Liberty Street.
(Photo from visitypsinow. Which is kind of funny. Because this place is in Ann Arbor.)


Is it a Weed or Is it a Crop?

  • Many home gardeners think of clover as a weed.  It does tend to spread, so people often get frustrated with this and rip it out.  And keep ripping it out -- it is rather persistent.
  • Some farmers, however, have a different opinion.
  • All those stories about cattle and bunnies loving to graze in the clover are apparently accurate.  According to the USDA, clover--especially white clover--is "highly palatable" and "nutritious" for a wide variety of grazing livestock.
  • You do have to be careful to keep the cattle from standing in the clover all day.  Because they'll keep eating it and eating it, and then they'll get the bloat.
  • As a plant for plant's sake, clover is a legume.  Its roots fix nitrogen in the soil, so it helps revitalize the soil.  Some farmers even call it a "living mulch," which means just by planting it and letting it grow, it will improve the soil it lives in.
  • Some farmers use it as cover in the space between crop rows.  For example, blueberry farmers in Michigan are discovering the benefits of planting white clover between the rows of blueberry bushes.  It doesn't compete with the berry bushes for sunlight, it out-competes other weeds, and it doesn't take much labor to mow it or seed it, since it often re-seeds itself.
  • Clover is also traffic-resistant.  This means you can walk on it, and you won't kill it.  It won't survive a lot of heavy livestock grazing, or a ton of foot traffic all the time, but it's also not so sensitive you have to avoid walking on it.
  • Bees love clover.  If you've got clover planted among your other crops that you want the bees to visit, the clover will act like a "POLLEN HERE" sign to the bees, and while they're there, they'll stop by your other plants and pollinate those too.


This bee is thinking, yum yum yum, clover

This bunny says, "What? Nobody here is eating clover.  I don't know what you're talking about."

This duck likes clover, too.

  • So you might see why the phrase "we're in clover" means we've got it pretty good.

Clover in Song

  • Of course, you can't talk about clover without this.  Please to hit play.




  • or the 80s version, if that's your fancy

Apple #704: Bloody Sunday and Selma to Montgomery

Yesterday, President Obama gave a speech commemorating the 50th anniversary of the march from Selma, Alabama.  There's been a lot of reaction to it, most of it positive.  There was also that movie about Selma, released recently, but which I have not seen.  I somehow manage never to get to the movie theatre these days.

I am embarrassed to admit this, but in listening to Obama's speech and in reading journalists' comments on it, I don't know what "Bloody Sunday" refers to.  I hear that and I think of the Troubles in Ireland (such a nice, delicate way of describing centuries' worth of Catholic vs. Protestant bombings and murders).

But of course I know that these speeches about Selma, Alabama, can't be talking about Ireland, that they mean events that took place during the civil rights protests in 1965.  But that's about all I know.

So what did happen in Selma, Alabama in 1965?  And to give me a place to start, why Selma?



Now that I've read the whole story, I see how this Life magazine cover photo pretty much says it all.  The two guys in front of the two-by-two column of people are Hosea Williams (L) and John Lewis (R).
(Life cover image from Successimg.com)

  • The Civil Rights Act was passed in 1964.  That was supposed to stop people and communities from discriminating against other people on the basis of race or color or sex or religion or national origin.  One of the ways people weren't supposed to be discriminated against was in matters related to voting.  But in fact, even though the nation-wide law of the land forbade it, many communities were still preventing people -- mainly African Americans -- from voting.
  • One of the places where this was happening most egregiously was in Selma, Alabama.  Some sources say only 2 percent of Selma's eligible black voters were registered to vote; other sources say less than 1 percent.
  • Selma was the county seat of Dallas County and the county sheriff, Jim Clark, had been very vocal in his opposition to blacks being allowed to vote.  He went around wearing a button that said "Never," meaning never allow black people to vote.  At one voting rights demonstration, he rounded up all the protestors using cattle prods and forced them to march faster and faster until a number of the protestors vomited.

  • He was friends with people in the KKK, and he organized a posse -- literally, a posse -- of KKK members alongside police officers to stand around in front of places where black people were going to register to vote.  His posse guys were also armed with billy clubs and cattle prods.  
  • African Americans who had shown up to these registration drives either to register or to demonstrate and encourage others to vote were harassed, shouted at, threatened, or beaten.
  • There were two locally-organized groups that were trying to prevail in spite of this neanderthal.  These two groups were called the Student Nonviolent Coordinating Committee (SNCC) and the Southern Christian Leadership Conference (SCLC).
  • It was around this time that Dr. Martin Luther King was informed of what was happening in Selma.  He supported both groups' efforts and encouraged them to continue to conduct nonviolent protests against the practices of Jim Clark et al., to draw national attention to the problem, and to raise national awareness about the fact that people were still being kept from voting.


Martin Luther King, Jr.  You know who he was, of course.

  • Many of the demonstrations that the groups held, which took place in January and February of 1965, were conducted outside the Dallas County Courthouse. They were trying to bring the problem literally to the steps of the courthouse, which was supposed to uphold the Civil Rights Act, but was not. 
  • During one of these demonstrations, on February 17, sheriff Clark and his men, who were also joined by state troopers sent to Selma by Governor Wallace, decided to break up the march by beating the men and women who had assembled with their billy clubs.  This was nothing new, really.  They had responded to other demonstrations in similarly violent ways.
  • On this particular evening, some of the demonstrators tried to get away from the troopers with clubs by running into a cafe.  But the troopers followed them in and started whaling on an older man, someone's grandfather.  His daughter rushed to the man's aid, and the trooper knocked her down.  Then her son, Jimmy Lee Jackson, stepped in and tried to protect his mother from being hit some more.  The state trooper responded by pulling out his gun and shooting Jackson, point-blank, in the abdomen.
  • Jackson, a 26 year-old church deacon, died of his wounds eight days later.

  • One of the organizers of the SCLC, Reverend James Bevell, said they should take the body of Jimmy Lee Jackson in a funeral cortege all the way to the state capitol, Montgomery, to show the state of Alabama and the country at large what had happened.  In discussing this idea and planning how to make it happen, they decided it should be a march from Selma to Montgomery.

This is what the first march looked like, coming over the bridge from Selma, led by John Lewis and Hosea Williams.

  • On March 7, led by the SNCC and the SCLC, some 600 people gathered at a church in downtown Selma, knelt together in prayer, and then began their march walking two-by-two through Selma, intending to go all the way to Montgomery, which is about 50 miles away.
  • The road from Selma to Montgomery goes south out of Selma before it cuts east. The southern edge of Selma is bounded by the Alabama River.  The bridge going over the river is the Edmund Pettus Bridge.  So essentially, once you cross the Edmund Pettus Bridge over the Alabama River, you're outside Selma, with about 49 1/2 miles to go to Montgomery.
  • The 600 marchers made it as far as this bridge when they were confronted by a blockade of sheriff Clark's men and his stupid posse and state troopers sent there by Governor Wallace.  I cannot believe, in 1965, there was a freakin' posse.  But there was.
  • The troopers and policemen and the KKK whatnots were armed with billy clubs and bullwhips, and they were wearing gas masks.  In other words, they showed up ready for a fight.


What was waiting for the marchers
(Photo sourced from crmvet.org)

  • A state trooper named Major Cloud got on his bullhorn and told the marchers that this was the end of their demonstration, that it was unlawful, and they had two minutes to disperse.
  • Well, it wasn't unlawful at all.  So the marchers did not disperse.  They didn't do anything else, either.  They didn't rush forward or do anything threatening.  They just continued to stand there.  
  • But this apparently was unacceptable to Major Cloud because he gave the order to the troopers to advance, and they did.  They pushed their mass of people into the two-by-two line of marchers and pushed them down like a steamshovel knocking down bowling pins.  And then they started hitting people.
  • They beat people -- men and women -- with their billy clubs.  They released their tear gas and clouds of it were everywhere.  It was pretty much a nightmare.

  • Multiple people were beaten, in the head, in the face, on the back.  They walked away with bloodied faces and broken noses.  One of the fifty-eight people beaten severely enough they had to be treated at a local hospital was John Lewis, chairman of the SNCC.  His skull was fractured.  
  • Here is an excerpt from his testimony given in a federal hearing following this march.  The guy questioning him is an attorney.
Lewis: I was hit on my head right here.
Hall: What were you hit with?
Lewis: I was hit with a billy club, and I saw the State Trooper that hit me.
Hall: How many times were you hit?
Lewis: I was hit twice, once when I was lying down and was attempting to get up.
Hall: Do we understand you to say were hit . . . and then attempted to get up and were hit—and was hit again.
Lewis: Right.

  • At the conclusion of the hearing, Judge Frank Johnson, Jr., ruled that the demonstrators had a constitutional right to march.  Which means the troopers and Clark and all the rest of those hooligans in uniform had no right to do what they did.
  • All this might have passed by the notice of most people in the country, making it only in a few newspapers, except that cameramen from TV news stations were there and filmed the whole thing.  So it was broadcast on TV news around the country.  And people across the country who saw this footage were horrified.
  • I found some of this footage so you could see it for yourself. 

This is an excerpt from some historical documentary, beginning with a description of what was happening in Selma leading up to Bloody Sunday.  The guy pointing his billy club at the camera is Sheriff Jim Clark.  Toward the end is footage from Bloody Sunday itself.




The first 3 minutes of this video show, without commentary, some of the footage from Blood Sunday.


  • Dr. King was sending out telegrams and press releases and public statements, decrying the response of law enforcement, and calling on religious leaders across the country to join their cause.  They would try their march again, he said, and the more people who would join their nonviolent demonstration, the better.
  • That same judge who said their first march was lawful told Dr. King he was going to issue a restraining order to prevent the march from going forward, at least for a few more days, until March 11.  He wanted enough time for a federal court order to go through so that a different batch of lawmen could be dispatched to Selma to provide protection for the marchers against Clark et al.
  • Dr. King sort of did and sort of did not do what the judge said.

The Second March -- March 9

  • Two days after Bloody Sunday, somewhat against the orders of the judge, Dr. King led 2,000 plus people -- note that the number more than tripled in two days -- as far as the Edmund Pettus Bridge.  There, they stopped and knelt to pray.  Then they turned and went back to Selma.
  • The troopers were still there, at the far side of the bridge.  By not crossing the bridge, the marchers did not antagonize the troopers.  But they also did not back down from their own decision to make some sort of demonstration. And it was peaceful.
  • At some point on this day, King gave a speech which included the statement, "I would rather die on the highways of Alabama, than make a butchery of my conscience."  Strong stuff, Dr. King.
  • By this time, President Lyndon Johnson was very well aware of everything that was going on.  He promised, in the wake of the second march, to introduce legislation that would specifically guarantee voting rights, and that he would do so within a matter of days.
  • A white Unitarian minister named James Reeb was one of hundreds of people who had seen the coverage of Bloody Sunday on TV and who flew to Selma to participate in the demonstrations.  The night of March 9, he and two other Unitarian ministers were eating in a restaurant in Selma that served both whites and blacks. After they left that restaurant, they were walking back to a meeting that would be led by Dr. King when they were attacked by "local whites."
  • Reeb was beaten severely in the head with a club.  Somehow, it was several hours before he was brought to a hospital in Birmingham, where doctors performed brain surgery.  But to no avail.  The Unitarian minister, born in Kansas and ministering in Boston, died two days later.  He was 38 years old.

  • Reeb's death galvanized many more people in the country.  If those "local whites" in Selma would kill a white man over this race thing, clearly they were way out of line.  
    • (You still see this sort of thing in movies all the time.  The black sidekick gets killed, because he's expendable, and this is what spurs the white hero into action.  Or a bunch of black guys in the background get shot, but it's only when one of the white guys who actually has a speaking part gets wounded that the white hero really gets ticked off and starts kicking ass and taking names.  We've still got a long way to go.)
  • All sorts of things started happening.  Johnson addressed Congress, saying, "Their cause must be our cause too. Because it is not just Negroes, but really it is all of us, who must overcome the crippling legacy of bigotry and injustice. And we shall overcome." More importantly, he submitted his voting rights legislation to Congress on March 17.
  • The Selma demonstrators submitted a detailed plan, describing their plans to march from Selma to Montgomery, to that judge, Frank Johnson, Jr., and he approved it.  He then called up Governor Wallace and asked him to call off his dogs -- er, troopers.  But to be on the safe side, the federal government also sent hundreds of Alabama National Guardsman to protect the marchers.

 The Third Time's the Charm

  • The third march set out on March 21.  This time, there were 3,200 people. Some sources say there were 8,000, but the judge said they had to limit the number to 300 people at a time marching along the two-lane highway. This time, they were protected by National Guardsmen and members of  the FBI. 
  • They walked from Selma to Montgomery, covering anywhere from 7 to 17 miles per day.  They camped out at night on land belonging to people sympathetic to the demonstration.  By the time they got to Montgomery, the number of marchers had greatly expanded to some 25,000 people.

  • They reached he capitol building four days later, on March 25.  Dr. King delivered a speech on the steps of the capitol building.  It was here that he said the following:
"I know you are asking today, "How long will it take?" (Speak, sir) Somebody's asking, "How long will prejudice blind the visions of men, darken their understanding, and drive bright-eyed wisdom from her sacred throne?" Somebody's asking, "When will wounded justice, lying prostrate on the streets of Selma and Birmingham and communities all over the South, be lifted from this dust of shame to reign supreme among the children of men?" Somebody's asking, "When will the radiant star of hope be plunged against the nocturnal bosom of this lonely night, (Speak, speak, speak) plucked from weary souls with chains of fear and the manacles of death? How long will justice be crucified, (Speak) and truth bear it?" (Yes, sir) I come to say to you this afternoon, however difficult the moment, (Yes, sir) however frustrating the hour, it will not be long, (No sir) because "truth crushed to earth will rise again." (Yes, sir) How long? Not long, (Yes, sir) because "no lie can live forever." (Yes, sir) How long? Not long, (All right. How long) because "you shall reap what you sow." (Yes, sir)"

"How long? Not long, because the arc of the moral universe is long, but it bends toward justice."

  • After this speech, a delegation from the marchers tried to deliver a petition to Governor Wallace.  The doors of the capitol were blocked by -- who else? -- a line of state troopers.  The delegation asked that the petition be delivered to the governor.  They were told that the governor was not in.  They remained on the steps with the petition until one of the governor's secretaries came out and collected the petition.
  • Five months later, on August 6, President Johnson signed into law the Voting Rights Act of 1965.  As he signed this bill into law, he called the right to vote "the most powerful instrument ever devised by man for breaking down injustice and destroying the terrible walls which imprison men because they are different from other men." (and women too, I would add)

But It's Still Not Over

  • Although the march was ultimately successful in helping to secure a voting rights law for the entire country, and in bringing to the eyes of people across the nation the extent of violence that some bigoted people were willing to go to in order to protect their narrow-mindedness, this wasn't the end of the story.
  • The same night that the marchers arrived in Montgomery, there was yet another murder.  A housewife from Detroit, Viola Liuzzo, who had also seen the news about Bloody Sunday on TV and who came down to Selma to march in support, was driving a fellow marcher, an African-American teenager named Leroy Moton, back from Montgomery to Selma.
  • She was driving him along Highway 80 when another car pulled up next to theirs and, I think while both cars were still driving, a passenger in the other car pulled out a gun and shot at her.  The bullet struck her in the face.  She lost control of the car, understandably since she was probably dead at that point, and the car went into a ditch and crashed.  
  • The guys in the car stopped and got out and would have killed Leroy Moton too, except he pretended to be dead.

I would show you a photo of Leroy Moton from that time, but money-grubbing Corbis owns them all.  So if you want to see what Leroy looked like, here's a photo of him.

  • Three of the 4 guys in the car were members of the KKK.  The fourth guy was also a KKK member, but he had turned FBI informant.  The next day, the three KKK guys were arrested. (Why, why why did the informant guy let it get to the point where someone got killed?)
  • The three KKK guys were tried, but of course, since the dead person was a woman, they had to say it was all her fault.  People testified at the trial that Viola was a Communist sympathizer (her second husband was a member of the Teamsters, and she herself was a member of the NAACP), that she had gone to Selma to have sex with black men, that she was a drug addict.  The old trick of making the victim look guilty, and when the victim is a woman, they call her a slut.
  • The KKK members were all acquitted by an all-white jury.
  • There was another trial years later, on federal charges.  Two of the 3 guys were convicted and sentenced to 10 years. The third guy died before he could be sentenced.  The two guys in prison later said it was the informer who did the shooting, but it was too late. The informer had been granted immunity, so things were left as-is.
  • In the meantime, Viola's family were sent letters filled with phrases like "N---r-lover". Her children were called "N---r lover's baby" and had rocks thrown at them.  Ladies' Home Journal polled its readers, asking them what they thought of Viola, and the majority said she was not a good mother, should have stayed home, and minded her own business.  Her husband became an alcoholic and died.  Her children suffered from post-traumatic stress disorder.
  • I'm getting a little off-track here, because I'm getting incensed.  
  • It wasn't only Viola and her family who continued to suffer despite the eventual successes of the march from Selma to Montgomery. As we've all seen more recently, in the Trayvon Martin case in Florida, in Ferguson, Missouri, in the Eric Garner case in New York City, too many African Americans are still suffering violent acts perpetrated against them because of racism and bigotry.  We as a country have made some improvements since slavery, and since 1965.  But we still have a long way to go.
  • Here's another bit of proof of that: about 4,000 bags, each containing a rock and a KKK flyer, were thrown onto the doorsteps of houses throughout Selma on the 50th anniversary of the march to Montgomery.  The fliers contained all sorts of "statistics" (a.k.a. bullshit) about the likelihood of this or that non-white race to commit this or that type of crime.
  • Robert Jones, the grand dragon of the Loyal White Knights of the KKK said to a reporter from the AP, "We pretty much put out fliers, some against King and some against immigration. It's time for the American people to wake up to these falsehoods that they preach about MLK."
  • He was also hoping the fliers would attract new members.  "The Klan is still out there and we are watching," Jones said.
  • Makes me sick.

The Moral of the Story

  • Vote.  People died for your right to vote.  Not just in the Revolutionary War, not just in the Civil War, but only a few decades ago.  And the struggle continues today.  
  • Very few countries in the world allow its entire citizenry to vote, and even fewer have fair and not-rigged elections.  This is a right that everyone should have, but very few people in this world have it.  We--all of us in this country--do have the right to vote.  It is an enormous privilege, hard-won by the lives of countless people who came before you.
  • The first and best way to make your voice heard is to vote.  If you're still not satisfied, get people together and demonstrate -- peacefully.  Show people what the problem is and present them with a solution.  If you get enough people to see the wrong that's being done, sooner or later, the rest of us will hear you.  And in this country, as President Obama said in his speech, we are committed to improving our laws and ourselves so that everyone will one day be treated fairly. As we all know deep down everyone should be treated.  And the KKK be damned.

P.S.

Apple #703: Pink Lemonade

I got the idea this weekend that pink lemonade cookies might taste good.  I thought they might seem light and refreshing and their color welcome in the middle of what has become a snowy winter.  So I looked around for a decent-looking recipe, and I'm making some tonight.  I've got a sheet's worth in the oven right this very minute.

While we're waiting for them to finish baking, let's find out about pink lemonade.



Strawberry pink lemonade.  It's kind of funny that people get all highbrow fancy about pink lemonade, once you know its origins.
(Photo and recipe from Fine Cooking)

  • The fact that it's called "pink" lemonade as opposed to some specifically-named fruit lemonade leaves the door open for whatever ingredient you want to use to make it turn pink.
  • Depending on your taste, you might want the pink in your pink lemonade to be made from:
    • Raspberry
    • Strawberry
    • Cranberry
    • Cherry
    • Cinnamon red hot candies
  • Here are some varying recipes for pink lemonade, to prove my point:
CHOW's raspberry lemonade
(Photo and recipe from CHOW)

  • But which, you might wonder, is the "real" pink ingredient?  How was the original pink lemonade made?
  • Well, there are all sorts of stories about the first pink lemonade.  As is often the case in identifying firsts, no one is exactly sure which version came first, or which one is the truth.  But all the stories have the whiff of the much-embellished about them.  So I will present all of them to you and leave it to you to decide which one you like best.
  • Just Plain Dyed -- in 1857, a guy named Pete Conklin who sold lemonade and other beverages at a circus concession stand happened to run out of water to make his lemonade.  Being an enterprising sort, he dashed about the tents looking for more water. In his search, he came across a woman named Fannie Jamieson, one of the women who rode horses on bareback.  She had just put her pink tights to soak in a vat of water, and the aniline dye from her tights turned the water pink.  


This is the sort of bareback rider we're talking about.
(Saturday Evening Post cover image by Norman Rockwell, from the Normal Rockwell Museum)

  • Mr. Conklin took the vat of pink water back to his concession stand, mixed up more lemonade, and sold it as "fine strawberry lemonade." He did a rousing business.  
  • Some versions say he didn't notice the water had turned pink until he'd already mixed a batch; other versions suggest he knew it was pink all along.  Either way, by the second batch, he knew what he'd done, but he kept right on mixing more.
    • I want to note here that it was quite common for a long time for lots of food and drink to be adulterated -- milk to be watered down, butter to be made of watery milk and marigold dye, all kinds of stuff like that.  It wasn't until the early 20th century when lots of regulations were passed that said the food & drink you sold had to contain what you said it did, and no toxic stuff either.  So it wasn't much of a stretch for Mr. Conklin to sell lemonade dyed with dirty tights-water as "fine strawberry lemonade."
  • Red Hot Lemonade -- Another circus fellow, Henry E. Allott, better known as "Bunk Allen," was a Chicago saloon-keeper, a gambler, and a circus promoter. He was something of a public figure, in the sense that he got arrested a lot, because the New York Times ran his obituary when he died in 1912.  There, they reported that Bunk invented pink lemonade when he was a teenager (which would have been around the 1870s).  One fateful day, while mixing up the original yellow lemonade, he somehow dropped in a bunch of red-dyed cinnamon candies by accident. "The resulting rose-mixture sold so surprisingly well that he continued to dispense his chance discovery," the NYT obituary said.


Try putting a bunch of red hots like these in your lemonade, and let me know if it's at all edible.  Or drinkable.  Cinnamon pink lemonade is the one variety I couldn't find a recipe for.
(Image from Wikipedia)

  • Sounds to me like this guy was a rum-runner during Prohibition, and he started his life of selling the illegal hooch early, when he was a teenager.  The lemonade was probably a mixer for something a little more potent -- gin, maybe.  The cinnamony-pink lemonade would have been a novelty to his customers, who might also have been looking for something to disguise the harder stuff mixed into it.  "Relax, Copper, it's only pink lemonade."
  • That previous paragraph is all my reading-between-the-lines supposition, of course. 
  • It is reported, however, that Bunk Allen said on his deathbed that he didn't want a priest, but that "When I'm planted, I want everybody to have a drink on me."

Perhaps what we should drink on Bunk Allen's grave should be a glass of Rachael Ray's pink lemonade with gin and ginger ale.

  • Whoops, I Dyed it Again --  Another circus dude, this one named W. H. A. Tobey, said he came up with pink lemonade by accident, in the 1860s.  His story is remarkably like Conklin's pink-tights-dyed lemonade, except Tobey's story removes him from some of the blame of selling an adulterated substance, and it has more signs of the tall tale about it. 
  • His story goes that he was working with a circus called Forepaugh's, and they were touring the Southwest.  Water was so scarce ("How scarce was it?") they didn't have enough water to sell lemonade. When he went to check on the horses, he got an idea.  He says a red blanket had fallen into their water trough, dyeing it pink, and the horses wouldn't drink the water.  So he brought the pink horse-blanket-water to the lemonade salesman, they mixed up a batch of lemonade with it, and sold it as colored lemonade.  Horses wouldn't drink the water, but people sure drank the pink lemonade.  It was such a hit, Tobey and the lemonade man made their pink lemonade at every stop after that.

  • Dye it One More Time -- Yet another circus man said he was the one who came up with pink lemonade.  This time, it was a guy named William Henry Griffith (not the Welsh-Anglican cleric), and his story removes him almost entirely from blame.  He says he had a batch of lemonade all mixed up and ready to go when, lo and behold, what should occur but a pair of a circus performer's red tights blew off a clothesline and into his vat of lemonade.  
  • What was he to do?  Should he have fished out the tights and mixed up a new fresh batch?  Never!  The tights must have dyed the lemonade instantly, rendering it impossible for him to undo the damage, and a customer must have happened by at that very instant, parched from thirst, begging for life-restoring lemonade immediately, and hang it all if it was dyed pink, the customer must have that essential lemonade.  And what do you know, the customer found it delicious, rejuvenating, even, and so what choice did Griffith have but to sell that red-dyed lemonade?  It was never his fault at all the lemonade wound up dyed, no sir.  
  • Again, I embellish.  But only to point out the latent but too-obvious ridiculousness of his story.


Pink tights, hanging up to dry. Are these the real inventors of pink lemonade?

  • Well, it seems pink lemonade has a none-too-savory past.  (Which makes sense, since it's very sweet, har har.)  But it does seem likely that pink lemonade was first mixed by some circus beverage-seller, and that its popularity spread across the country as the circus(es) made their rounds.  Which would explain why no one is exactly sure where it appeared first or most memorably.
  • Now for the cookie update.  Alas and alack, my cookies are turning out like crap.  They're hard little knobs that won't spread out on the cookie sheet, and they don't have much flavor.  I suspect this is my fault, not the fault of the recipe.  Because I monkeyed with it.
  • I doubled the recipe, first of all, which doesn't usually create problems.  But then I wanted more lemonade flavor, so I added some lemon juice.  Not quite enough lemon flavor, so I added some lemon extract.  That helped, but it seemed overly sweet, so I added a quarter teaspoon of salt, which I thought brought out the tartness.  The extra lemon juice seemed to have made the batter too moist, so I added some extra flour.  And I think this is where I ran afoul.
  • So I will spare you photos of my sad knobby little cookies.  Instead, I will direct you to the recipe I used and instruct you to adhere to the recipe more closely than I did.  I'm sure your cookies will turn out better than mine. 
Pink Lemonade Cookies, recipe from Better Homes and Gardens


This is what the BHG cookies should have looked like.  The cookies in this picture were made according to Betty Crocker's recipe, which calls for a sugar cookie mix.  I don't like using mixes, but if you do, this might be a good choice for you.

Apple #702: 3D Printing

The university where I work recently acquired two 3D printers, and they sent out a call to any students or faculty to submit requests for objects to be printed on it, for free.  This deal was supposed to last for 2 months, and they've already had over 500 requests, more than they can fulfill in the 2 months.

When I first saw the notice go out, I thought I'd like to submit a request, and I thought I'd pick something really hard, but also something I actually wanted.  Like a piano.  I thought that would really knock them for a loop.  But then I found out that people have already made pianos with this 3D printing technology.  Incredible stuff.

I don't really understand the whole 3D printing thing, so I'm going to try to find out how it works.  I'm sure I will miss the nuances of the technology, but I'll try to give you (and me) a basic overview, a starting point.  Off I go to do my research. . . .



This dress was printed using 3D technology. It is made of links of material that interlock together on tiny hinges. The pieces can be custom-assembled so the dress fits anybody. MoMA thought the idea was so cool, they bought the technology immediately.

3D Printing is Rapid Prototyping

  • 3D printing has actually been in use since the 1980s.  1984, or 1986 or thereabouts.  But it wasn't something the general public knew about; it was a technique manufacturers used, and they called it "rapid prototyping."  You might have heard this phrase before without really knowing what it means.  I know I did. 
  • Rapid prototyping/3D printing allowed manufacturers to create a model of a part or some specialty piece that they weren't sure how it would work and test it out.  They could make one of these things, without having to go through a huge assembly line and make a ton of them, so they could customize whatever part and try out, without a lot of overhead.  This is the "prototype" part.  And, since they were only making one, it could be done quickly -- the "rapid" part.  It's not part of the name, but this one-off method was also a whole lot cheaper than making a batch of parts they weren't sure would work or not.
  • So manufacturers leaned a lot from the parts they made using rapid prototyping -- what we now call 3D printing.

 
In the past, this is how rapid prototyping was mainly used: to create customized, detailed parts, pretty much on a one-off basis. These bits and pieces are used on airplanes.
(Image from IFExpress)

  • An additional benefit is that it builds a product in a completely different way than old manufacturing techniques.  The older methods would basically take a big sheet of metal or plastic and punch holes into it or cut details out from it.  3D printing uses  a computer to build a custom shape out of the materials and pile the materials on top of each other. Think of a chain link fence, for example.  That has to get made as wire, which is then cut and bent and molded into shape. With 3D printing, you could basically build a chain link fence from the bottom up, not from bits of wire folded together, but from layers that are fused to form one solid object that is your fence.
  • In the past couple of years, this technology is getting used for more and more things -- everything from space station parts to prosthetics. As it's becoming more commonly used, we general-public, non-manufacturer people are starting to hear about it.  Since the technology is used not just for manufacturing test parts, but for entire objects, "rapid prototyping" isn't really an accurate phrase anymore.  It's much broader than that.  So people are now calling it 3D printing.


Now, 3D printing is being used not just to make test parts for vehicles, but to make entire chassis components, functional elements in the engine or drive train, and even to make the entire vehicle.  I'm not sure if this company made this entire motorcycle using 3D printing, but I think they made at least most of the parts with it.

The CAD Part

  • But, OK, you want to know, how the heck does it work?
  • In brief, it is lasers or some other really hot technology that zaps little bits of plastic to fuse them together according to a computer-programmed plan, and what you wind up with is a three-dimensional plastic object. 
  • Because the technology relies on a computer to tell it what to do, you first need a program.  Or a plan.  This you get from CAD (Computer-Aided Design).  Using CAD, you make a computer-rendered three-dimensional representation of the object you want to create.  This is the blueprint for your object of choice.
  • It used to be, to make a CAD drawing, you needed to buy really expensive CAD software. Not these days, and not for 3D printing.  There are lots of places online where you can design your own 3D objects to be 3D printed -- for free.  TinkerCAD is one of those places.
  • Here are some examples of people's CAD designs:

  • Starting to see the possibilities?
  • On a lot of these sites, not only can you make your own CAD design, but for those of us who are less 3D-minded, you can also download designs that other people have already made.  Sometimes there's a fee, but usually, you can download the design for free.
  • The next thing to do is send your CAD design to a 3D printer.  There are some 3D printers available for you to buy at home, but based on the little I've read, they're still pretty limited and small, and if you want to make something substantial like a piano or a guitar or a saxophone, you're better off having an industrial-sized machine print it for you.
  • How do you find a 3D printer that will take your CAD design?  Well, TinkerCAD will also 3D print your design for you -- for a fee, of course.  But there are many other places that offer 3D printing, including:
    • UPS stores -- when they first rolled out their 3D printing services in 2013, it was only for small businesses, start-up companies, and retail businesses near San Diego. They've now expanded to over 100 locations.  You'll want to find out if your location will serve anybody, or if you have to be a business to use the service.  It could be cost-prohibitive for individuals.
    • Shapeways -- seems to specialize in small objects like gadgets, jewelry, toys, and, yes, My Little Ponys


This Kosmoceratops will set you back $120 to have it 3D printed with rose gold plating.

    • i.materialize -- lets you upload your designs, but also has a team of designers on hand who make and post new designs regularly, so there are often new products to choose from.

    • Sculpteo -- they don't have a lot of designs to start with, but mainly support you and your designs that you can upload to their site, get a quote, and ask them to print them for you.  They will even tell you if there's something wrong with your file, and fix the problem for you.
  • These are only a few of the many 3D printing services out there.  To find a 3D printing service near you, check out 3D Hubs

The Printing Part

    • How does the printing actually work?  This is where things get more technical.
    • Basically, a 3D printer makes layers on top of layers of plastic that get fused together so you wind up with a solid plastic object at the end of it.  That's why this is sometimes called additive manufacturing, because it's adding one layer on top of another.
    • That is a very simplified explanation.  For more details, read on.
    • There are several different methods of achieving a 3D-printed object.
      • Selective Laser Sintering -- the key word here is laser.  This type of 3D printing uses a laser, beamed at a heap of powder, which can be made of plastic, or ceramic, or glass, or metal.  The laser, following the CAD instructions, zaps the powder to create a thin, solid layer of the object. Then it spreads another thin layer of powder on top of the first layer and, again, according to the CAD instructions, zaps that to melt the powder into another layer.  Repeat until the object is complete.  This method seems to be the most commonly used.  You can see how the process works in the video below.

    Video of selective laser sintering starts at about 3:20. Includes lots of interesting description of how the product is cleaned up and painted as well.



      • Fused deposition modeling -- picture a glue gun, but one that melts plastic instead of glue.  This uses a filament (long thin strand, like a wire) of plastic or metal, which is fed into a nozzle that heats the plastic or metal, and can be directed either by hand or by computer.  Industrial versions of this method layer the extruded lines of plastic or metal one on top of the other to create a solid object.

    This guy is trying out a 3D printing pen for the first time. The pen uses fused deposition modeling.  He has trouble getting it to do what he wants, but I think it's because he's not layering the plastic, he's drawing individual lines with it like you would do with a pen.




    This video gives you a better sense of how fused deposition modeling works on a more industrial scale. The music is super-over-dramatic, and the camera gets out of focus a lot, but you get a good sense of how the machine puts down the layers. Unfortunately, his knife can't really cut paper, but that's probably due to the design, more than the technology.




      • Stereolithography -- this method also uses a laser, but instead of zapping powder, it zaps liquid.  The liquid is a special polymer that will change in response to light -- in this case, it will harden when zapped with a laser.  A polymer can be lots of things (rubber, silicone, PVC, nylon, even silk or wool), but I think the special liquid polymers they use here are mainly plastics.

    A rather old-school animation showing how stereolithography works. I suspect this method is not one that has found its way to more customer-facing applications but is rather still used mainly by large industrial concerns. i.materialize has a ginormous stereolithography printer, but they use it to print entire batches of an object all at once.



    • There are a couple of other methods, but they are mainly variations on those 3.  I'm sure as use of this technology expands, engineers will develop still more techniques and refinements.
    • Now you know the basics of how 3D printing works.

    More Applications

    I didn't start to get excited about this until I saw some of the things you could make with it.  And I think seeing these 3D-printed objects helps you get another sense of how it all works.  So here are some more applications for you to noodle over.


    Video of 2 guys from Fender talking about how they're using 3D printing, and how they hope it can help them to uncover new tones and sounds. They're also playing some of their 3D-printed guitars. Pretty cool.




    The guy who made the guitar with stars in the body also made a saxophone. This is his first crack at it, so the results are imperfect. But I'd say it's pretty good for a first try. He says it's made of nylon, and it weighs about 1/4 of what a typical saxophone weighs.




    I seem to be especially interested in musical instruments, but there are all sorts of other applications. Prosthetics is one area that's seeing a lot of 3D printing. Prosthetic limbs need to be highly customized to each person in order to fit correctly, and it's much easier to achieve that customization with 3D printing than with conventional manufacturing methods.

    This prosthetic hand combines robotics and 3D printing to make a lightweight plastic hand that is flexible, durable, and customizable. The video mainly discusses the robotics, but you can see how it was 3D printed. It looks like the 3D printing method used is fused deposition modeling. The video turns into a fundraising message, but you can quit watching at that point because the fundraising campaign has ended.




    These two guys just ate 3D-printed food. They can't get over it. The 3D food printer is loaded, not with plastics, but with edible ingredients. It takes some attention to detail, not because of the intricate shapes it can produce, but because different ingredients have different textures, consistencies, and temperatures. But ever since NASA 3D-printed a pizza, lots of companies have started taking a whack at this.  Sources say to expect 3D food printers available for purchase by the end of 2015.




    Here's the 3D pizza printer at work. There's no sound in this video.  But you can see how the crust is layered, then the sauce, then the cheese. The result is a bit sloppy, but apparently the whole thing is cooked in the process of being printed.




    There are also people who are making 3D-printed guns and knives and other weapons that have varying degrees of efficacy. 

    But I would rather end with Derby the dog, who got a pair of prosthetic paws.
