Web Videos Show Off the Wonders of Chemistry

Television 93

Timmy writes "Wired Science has picked ten of the best videos from YouTube and their own show on PBS to highlight the wonderful things chemistry can do. Only four of them involve fire or explosions. The rest range from music videos about the polymerase chain reaction to reactions that repeatedly change color. One shows how to pour sodium acetate stalagmites. Another shows Chris Hardwick giving instructions for building a glow stick while making absurd comments."

Most things are accessible if you're creative enough. The benign stuff you can just buy outright from a chemical supply store. Now that the interwebs are available to the unwashed masses, the nasty stuff can be improvised.

My friends' 10-year old daughter was complaining recently about inaccessible chemicals interfering with her science fair project. (She wanted sulphuric acid - Her mom insisted on lemon juice because she "didn't want to be put on a list"). Her mom complained (half-heartedly - mostly in fun) after I told the girl that hydrochloric acid could be purchased without ID under the name muriatic acid and that sulphuric acid was readily available from car batteries and could be concentrated by boiling it until white smoke appeared. I even took the extra precaution of pointing out the need for proper ventilation.

I'm straying off-topic, but when on a roll...

Seems to me that using dangerous chemicals along with kids is preferable to what I did as a youth - Swiping them off-hours from the school chem-locker, stashing them in the closet, and experimenting unsupervised. On a related note, the first time I tried to swipe gasoline by storing it in a Styrofoam Sonic cup was messy, but an open door into a whole new kind of fun.

For me, one of the most memorable (certainly not the most dangerous or biggest injury inflicted, just memorable) was when my parents were gone and I managed to set fire to the surface of a large jarred candle. Mind you, once all of the wax in a candle is melted and the surface has actually caught fire, water is a bad idea. The wax boils and begins shooting flaming wax balls out. Then the glass shatters. Major bummer and hard to explain when the parents notice the huge charred area on the porch.

Ya know, one day someone is going to make a machine that can make illicit drugs and rather than use it to undercut all the gangsters and try to take over their "turf" they will just publish the details on the web. If you genetically engineered bacterium to produce these drugs from sugar or whatever there would be no "precursors" required and so all the techniques police currently use to track down drug creators will be just impossible. The flood of high quality (read: uncut) drugs will put all the scumbags out of business and negate most of all the negative effects of drugs on society.

This same ideology can play out in the plant kingdom as well, a large number of psychedelic drugs are directly produced by plants, or use plants as the precursor.

Ephedra sinica - > plant produces ephedrine, precursor to methamphethamine
Sassafras albidum -> produces sassafras oil, which contains large amounts of safrole, used to produce MDMA (ecstasy)

The list goes on and on and on...

As for precursors, there's enough entheogen producing plants :)

The colour change one is actually much more interesting if carried out right. Around 1980 when I was doing my A level chemistry, I found a Scientific American article about these reversible reactions, and took it in for the chemistry teacher to see.

More interesting that stirring a beaker, is to mix the ingredients in a shallow glass tray. The reaction starts spontaneously at several point and then concentric waves of colour radiate out from these points, interacting with each other. It's rather like watching a Conway's Life-style cellular automaton.

A friend of mine likes to tell the story of how when he was in high school chemistry, he did a little bit of studying of the periodic chart and found a variation of thermite that was much worse. With the instructor's approval, they made up about a teaspoon of the stuff. Then, the instructor (who really should have known better) put it on a lab bench on an asbestos pad and lit it off. Not only did it scorch the bench, it scorched the ceiling! And no, I'm not going to tell you what they substituted for the iron oxide; not only is this stuff dangerous, the byproducts are, and that should be enough for you to figure it out for yourself.

Re:Thermite - One concoction to rule them all... (1)

techno-vampire (666512) | more than 6 years ago | (#22621176)

Nope! His concoction isn't useful partially because it's too toxic (not always important in a military application) and partially because thermite's already hot enough for what they need. Not being a chemist, I doubt he's ever published, although what I said in my original post is probably enough to let a chemist figure it out.

Re:Thermite - One concoction to rule them all... (1)

PitaBred (632671) | more than 6 years ago | (#22629054)

Or possibly because iron is all over the damn place, and making iron oxide isn't hard, whereas many (most?) other metals that would supply the proper amount of oxygen aren't really available in large quantities easily?

Re:Thermite - One concoction to rule them all... (1)

gnick (1211984) | more than 6 years ago | (#22621102)

The story's interesting - Its authenticity, IMHO, is unimportant. I'm sure that there are better metal-oxides to combine with aluminum powder to make thermite - Ferrous oxide (rust) is the most convenient, but any metal compound that provides a sufficient amount of oxygen for the aluminum to burn oughtta work. I'm curious - Sure you don't wanna share details? What's the worst that could happen?

Re:Thermite - One concoction to rule them all... (1)

techno-vampire (666512) | more than 6 years ago | (#22621190)

Sure, I'll share, but only by telling you how he worked it out. He noticed that the reaction heat went up as the atomic weight of the oxide did, and looked at the next element in the same family as iron.

Re:Thermite - One concoction to rule them all... (1)

Cyberax (705495) | more than 6 years ago | (#22621320)

There's nothing complex about it, you can create more powerful thermite mixes with additional oxidizers (like potassium permanganate or potassium nitrate). They are described in a lot of chemical literature, there's nothing secret in it.

Of course, all this stuff is incredibly dangerous - it can burn through almost ANYTHING.

Re:Thermite - One concoction to rule them all... (1)

pirho666 (153073) | more than 6 years ago | (#22621920)

Yeah, but osmium tetraoxide melts at a much lower temperature as well, so the reaction will rapidly become a nice sludge, thereby also increasing the rate. Osmium will make you go blind though, but that is almost like winning a darwin award, so be sure to try it at home kids.

techno-vampire (666512) | more than 6 years ago | (#22626714)

It's not exactly a secret. As I've said, anybody can work it out for themselves the same way my friend did. I just didn't want to spell ii out openly so that kids who didn't know how to work it out wouldn't find out.

Entertainment, not education (4, Insightful)

neapolitan (1100101) | more than 6 years ago | (#22620718)

From TFV:

"Adding something cold to thermite doesn't cancel it out, it just makes it angry."

Wow, just wow. We've talked about this kind of thing before in the context of CSI and Mythbusters.

I really wish that popular science shows would at least attempt to bring some education into the mix. I am not against blurring of education and entertainment, but the videos presented are simply bad entertainment. Why not give an elementary discussion of 'heat capacity' or energy that is associated with phase transitions, etc? It would still give the explosion of thermite and provide a small education.

Does anybody remember the old PBS series "3-2-1 contact" or "Square One?" It had education plus entertainment in a nice combination IMHO. What I would like to see is a Mythbusters-type show where they try to predict things *first* with introduction to physics / chemistry concepts, and then test their findings (with explosions and the hilarious consequences.) They do this a bit with their *Warning Science Content* segments, but it could be made a bit more rigorous.

Yes, I know the arguments that this is making kids "interested in science," but true research / science is very little about explosions, and these shows are, in my experience, not making kids interested in the rigor or reality of scientific reasoning. The question regarding thermite was proposed by a 30+ year old man!

you know, it's important to know concepts important to thermodynamics although it's infinitely more important and useful to understand the scientific method its self. The facts and theories are the result of the scientific method and would be pretty much unthinkable without it. knowing that we know something is not as important as knowing HOW we know something. It's always been something that has been lacking severely in the general population's understanding of science and it is also why pseudoscience has become as widespread as it has. There is a disconnect between the logic used to create knowledge and people's understanding of how their world works. If shows can find a way to start with the science using the scientific method and make that more entertaining than it will improve things a great deal.

The scientific method; potential misconceptions (1)

jonaskoelker (922170) | more than 6 years ago | (#22622226)

The facts and theories are the result of the scientific method and would be pretty much unthinkable without it.
Yeah.

Kinda. Depends on what you define the scientific method to be. [I'm reiterating a point made previously (http://science.slashdot.org/comments.pl?sid=466370&cid=22553660 [slashdot.org] )]. New scientific knowledge (and let's not go out on a cartesian limb here) is the product of two major components, one of them being being the design and execution of experiments combined with peer review.

The other is insights, ideas, and imaginations. There is no well-known algorithm, no "scientific method", by which we can generate ideas and infer connections in the data we observe. All we can do (as far as I know) is to take the ideas we generate and apply the first component, rigorous testing, to discard the ones of non-maximal usefulness.

This is elegantly summed up in the phrase "It is not the purpose of science to produce infinite wisdom, but to guard against infinite folly" [citation needed] (linked post says Brecht).

As an anecdotal example of what I'm talking about, it one day dawned on me that there must be a reason why code colouring is such a deal-breaking feature of editors (in the mind of most coders, at least), and that the reason is that colours are in some way perceived more readily (easier or faster). [That's the insight component]. Later, I listened to the an OCW intropsych lecture about visual perception, and indeed the lecturer made a few experiments (without the rigour part) with the class showing that:

1. Finding a red circle in a blob of green ones is fast
2. Finding a tee in a blob of ells is slow.
3. Finding a tee in a blob of ells is fast if there's a red tee, no red ells and a bunch of green letters (my assumption about the details).

Presumably, he could apply a bit of rigour and publish a peer-reviewed article containing "my" idea (only it's probably not that new by now).

The important point is: how did I come up with the idea? It just sorta' popped into my head, and no methodology could reliably have produced that idea.

Re:The scientific method; potential misconceptions (1)

wizardforce (1005805) | more than 6 years ago | (#22625702)

getting the idea in the first place doesn't have a method but testing that idea does. I would argue that the single most important difference between the time our technology advanced exponentially and the dark ages is the scientific method. People always had ideas- tons of them and no real method to test them. once they figured out how to evaluate claims they could make true use of these ideas. without ideas there is nothing, without the scientific method there may as well have been nothing.

Re:The scientific method; potential misconceptions (1)

PitaBred (632671) | more than 6 years ago | (#22629238)

Did you ever consider that when you're looking at very similar shapes and very dissimilar colors you've made a very silly experiment? Try something like picking the [0,0,205] blue ball out of the field of [0,0,255] blue balls (search for blue3 on this [njit.edu] page) as easily as you did the red? I'd also bet you could find the O in a field of T's almost as easily as you did the red ball in the blob of green ones, as long as you weren't colorblind.

But I'm betting that I'm just a peer in your scientific review process ;)

Mythbusters basically piss on the scientific method every time they put a show together. If it were presented as that I'd be fine with it.

...about how chemistry-as-a-hobby is increasingly a victim of the War on Terror (TM).

"War on Terror" is but the last nail in the coffin (1)

Ellis D. Tripp (755736) | more than 6 years ago | (#22622484)

, because hobby chemistry was pretty much destroyed well before 9/11. The "War on Drugs" caused most chemical sellers to eliminate sales to individuals, and in some states (like Texas) it is illegal to even own laboratory glassware without a permit (and regular inspections) from local police.

Add in the effect of lawyers and insurance companies (who drove chemistry sets off of toy store shelves), and you have one more "perfect storm" contributing to the ongoing "dumbing down" of the US.

chemistry (4, Funny)

Chemistry isn't as nearly as 'cool' as these pretty make-fire videos lead one to believe. Every explosion a young chemist commits brings them closer and closer the sad reality of their career later in life, performing volumetric titrations day in day out in labs with limited ventilation and no capacity to do dumb shit with metal sodium. Chemists are nothing more than glorified, poor cooks who use class 'A' glassware.

All the more reason to demonstrate all of the "dumb shit" that they can, enjoy it, and explore the fun-but-not-commercially-exploitable sides of their chosen path. Especially when it entertains the rest of us.

Cheers.

Only if you're too dumb to get a Ph.D. and do the cool stuff.
A BS in chemistry doesn't really get you anywhere good, unless you enjoy doing the same routine tests day-in day-out.

speaking of chemistry videos ***SPOILER*** (3, Interesting)

circletimessquare (444983) | more than 6 years ago | (#22620824)

i've really been enjoying Breaking Bad on amc

high school chemistry teacher gets lung cancer, decides to leave the world without saddling his family with debt, so he begins to make meth

in the episode i just saw tonight

***SPOILER***

he goes into a drug lord's den with a bag of meth. said drug lord isn't very impressed with the man and has put his partner in the hospital. so said mild mannered chemistry teacher, now unafraid of death, takes the "meth" he brought with him and throws it on the floor, hard

it's really fulminated mercury

BOOM

meth drug lord meets fulminated mercury beats any youtube chemistry video i've seen

I'd never heard of Breaking Bad. But, it looks OK. For anyone who's interested, episode 1 can be found here. [amctv.com]

Number 9 is potassium chlorate, not permanganate (1)

Joce640k (829181) | more than 6 years ago | (#22620848)

Potassium permanganate is purple.

Besides, even the video says "chlorate".

I think they could have used a bigger bucket of liquid nitrogen on number 10.

Two videos, two errors. Eight more to go...

I had to read the original line half a dozen times because for some reason it looked like Potassium Pomegranate.

I already had my juicer out too.

Wow, #2, biovisions was by far the best, IMHO. What a great concept and beautiful implementation. I'd love to see more of this type of stuff (going to Google it after this reply). Wouldn't it be great to have a "Google Body" where you could zoom in and zoom out on a simulated body?

I freggin' love this stuff.

Don't miss the Cell Video (#2) (0)

Anonymous Coward | more than 6 years ago | (#22621242)

IMHO, the cell video was one of the most beautiful things I have seen. While it did not attempt to ID every reaction that took place, it was a thing of wonder to see the self assembly of some long molecules, or to watch what seems to be a molecule come along, works its way down a gene, and then when it found the correct place, snip it off.

Somebody spent a long time working on that video, but it was really worth it.

Junk Science (1)

Sitnalta (1051230) | more than 6 years ago | (#22621592)

Brainiac is to a science show as a parakeet is to a velociraptor.

Seriously, I watched a season of it and was dumbfounded at the amount of misinformation and fake stunts they pulled. Once they put a fire extinguisher into a oven, and it exploded in a fireball shortly after. Yes, that's right. A fireball.

Mythbusters may err on the side of theatrics, but they never fake a result. And they have people who actually know stuff about science, instead of Richard Hammond.

Re:Junk Science (1)

Gregb05 (754217) | more than 6 years ago | (#22623212)

Was it a gas oven?
If so, they may have damaged the oven to produce a fireball, instead of magically producing one from a fire extinguisher.

Re:Junk Science (1)

Sitnalta (1051230) | more than 6 years ago | (#22626054)

No. It was an electric oven.

I found more chemistry videos online. They are pretty great and I learned new things from them. Check them out: http://www.sutree.com/Learn.aspx?q=chemistry [sutree.com]

Recipe for eternal Youtube hotness (0)

patio11 (857072) | more than 6 years ago | (#22621916)

One BlendTec blender, with blades replaced with sodium. One bag of Mentos, reduced to a fine powder with said BlendTec blender. One bottle of coke. One Chuck Norris action figure. And a VERY, VERY long stick to turn the blender on with.

(What do you need the Chuck Norris for? Oh, the question you should be asking is, what does he need you for. And the answer is, he doesn't need you for anything, so you'd better get running while you still can.)

I'm not sure (but I might be) that I represent most people my age... but if chemistry isn't your thing, then the ONLY way I'm interested in it, is if it involves fire and/or drugs.

Interesting! Steve Spangler anyone? (1)

careysb (566113) | more than 6 years ago | (#22622658)

Saw a couple of the videos but most were blocked from my proxy at work. I'll have to wait till I get home. In the mean time go to YouTube and search for "steve spangler". He has some entertaining clips on science experiments. He's beed on channel 9 here in Denver, and also the Ellen show.

Amazing Mercury Video (1)

Sir Holo (531007) | more than 6 years ago | (#22623258)

Another great video: Mercury Drop Experiment [mac.com]

A cyclic redox reaction on the surface of a drop of mercury causes it to wobble around. Chemical energy -> motion.

Click "Activity 3" or "Activity 5" for the coolest ones.

Color-Changing Experiment (1)

Controlio (78666) | more than 6 years ago | (#22623416)

Does anyone know the formula for the color-changing experiment? That amazes me, and assuming I don't kill myself or my neighbors in the process, I would love to try it out.

Plus, if anyone knows the recipe, do you also know the reaction that is taking place and why it happens repeatedly?

The other videos were cool, but that was the only one I just kept repeatedly staring at in amazement.
