What say the teeming?
When he takes a handful out, why don’t they all merge together? To me, it looks like he filled the bin with clear marbles (which don’t show up in water), and he merely scoops them out.
You want to see something, mix cornstarch with water.
The YouTube video is by a kid who can’t spell and doesn’t seem to know the first thing about science. That alone would lead me to doubt it. The WikiAnswers points to a website with these, which look a lot like balls in the video.
There is no reason I can think of why a tub of salt water should suddenly form “marbles.”
Sodium acetate is the salt used for the famous supersaturation demo in chemistry class, where you drip the solution onto a seed crystal and it precipitates out, piling up into a tower. What’s he produced in the video is not nearly that saturated, and it’s also still acid.
Calcium carbonate is chalk, (or limestone, or marble, or calcite, or Tums). There is no stable solid form of calcium bicarbonate, so I’m sure he didn’t have that. All the fizzing in the video is from the reaction of the residual acid and the carbonate.
And then there’s the salt: iodized or not, it’s just salt. When all is done, you’ve got water with lots of ions – calcium, sodium, chloride, acetate, and bicarbonate (HCO[sub]3[/sub]). There’s nothing there that’s going to make rubbery little balls.
There’s also the question of where the hell all that water came from; when he started, there was just an ounce or two of vinegar, and then there’s fizzing, and he adds salt and it knocks the foam back down to about three ounces, but when he ours it off, there’s nearly a pint. Whappen? It keeps growing, and growing, and GROWING!
It seems that this should be simple enough to test. Follow the kid’s directions and see what happens. I might try myself.
Of course, there’s always the chance that the kid actually did make the stuff, but didn’t document his procedure correctly.
He says so himself at the end of the video.
I’m guessing sodium polyacrylate. THat’s the stuff in superabsorbant diapers. You see it sold in garden shops and the like as a gel growth medium. It’s nearly all water, and has almost the same optical density, so it is very hard, but not impossible to see when in water.
Look at the scene, where he writes “almost ready” or just before he scoops some out. You can barely see there is something in the water. It doesn’t happen “when contact with air” the polyacrylate nodules are already there
Here’s what the kid seems to be using
Edit: Sorry #3 didnt see your link.
Plastic pie pan
10 grams of Jelly Marbles
**7 Dram vile **
3 Glass marbles
It could also be glass marbles, in some fluid other than water with the same index of refraction as glass.
What the heck is “polar hability”?
Sucks that this was debunked… if it were real, that would be really cool!
