    I am going to be with my great nephew Sunday. I am going to try it out with him. I think he will find it as cool as I did.

    That... um... seems rather elaborate for it's purpose.
    Maybe just freeze water in a mold instead?
    (Though I suppose getting a quick enough freeze that you don't get imperfections in the ice might be difficult??? Not really sure why you'd need that, though it looks like fun.)

    What the maker of the video doesn't tell you is that while the camera was off he threw out the goop that he made and stuck some of these in water (in which they become invisible):

    At 2:05 he's added some pink colouring, but you can see the round marbles inside the tub. The marbles are way too symmetrical and consistent in size and shape. Plus, when he digs his hands in, the round marbles are clearly showing!

    Yeah, I think you're right, it most likely doesn't work.
    I thought perhaps he was tweaking the presentation by pulling some out then putting them back in (and some reaction with air/accretion on the surface led to the structure being maintained after reimmersion and making for more dramatic effect) - but the perfect spherical balls is unlikely given the numerous forces acting on them, as is their consistent maintenance after reimmersion.
    Also, the science terms he used are just gibberish (I thought perhaps it'd been too long since I did chemistry, but checked).

    The basic idea is not entirely illegitimate (and I can imagine a combinatino of properties to provide similar effect - combine for instance sheer thickening fluid properties with high surface tension (which is (most often) a product of molecular polarity) - add a reversible polymerization or non-penatrating dehydration-like reaction [the two could combine nicely with if you had a fast evaporating depolymerizing agent in the larger bath] with air and voila, you get shapes. In zero gravity they'd be close to spherical. Of course, you'd have to cover the whole solution in another reagent to prevent it's surface mixing with the air - probably the biggest tell in the video, no evident surface tension when penetrating the fluid, despite being exposed to air). Also, a *little* (so maybe there's more) research seems to indicate others haven't gotten the experiment to work. [That doesn't mean it doesn't but all-in-all, looks like a cute con.]

    Anyway.
    For those of you who are saddened at this loss allow me to recommend this to cheer you up! :


    The Self-Made Tapestry, by Phillip Ball
    An excellent collection of fascinating examples of self-organization. (Discussing things from why glass (one of the hardest substances at the molecular level usually breaks easily), to chemical waves, to physical laws' impact on biological processes. Informative and very readable (you don't need to be a specialist). Probably one of a few formational books for me;

    http://www.amazon.com/Self-Made-Tapestry-Pattern-Formation-Nature/dp/0198502435

    And, here's a nice little self-organization experiment to tide you over. Or. In which clocks are evolved. (This makes me a little emotional ... and a little giddy icon_smile.gif )
    Evolution: courtesy of immutable mathematical law.
    Music: courtesy of Cold Play (not my favorite, but works for the video : )


    ps:Ariodante, as an intellectual you'd surely appreciate that all conclusions ought to be tentative, no? ;)

    The problem with that is that you'd get a seam mark on the ice ball where the 2-part mold to make it comes apart (basically just a thin ridge of ice, but it'd look kinda cheap). I suspect it wouldn't look as crystalline, either, kind of frosty and opaque.

    That's awesome!! I would do it myself if it didn't require so much work and materials. Don't judge my laziness!


    Well everyone seems to think it is fake. OP, how about you let us know how it goes once you are done and settle the debate?

    The chemistry behind this video is completely bogus. The coolest thing you can do with Sodium Acetate is make a super saturated solution, let it cool down to room temperature, and then add one crystal to the mixture. You will see a glass full of liquid immediately turn into a solid.

    I find this reaction to be much more amusing. Gummi Bear Torture!!!!!icon_twisted.gif

    Simply add one unlucky gummi bear to a test tube full of molten Potassium Chlorate and enjoy the light show!icon_cool.gif
