sodium acetate, super condensed.
the hand has a few crystals of sodium acetate on it, allowing the process to start.
what happens is that the sodium acetate is already past its capacity for a liquid, and adding more pushes it over the limit and makes it start solidifying.

sorry i cant help more. ive used up all my brain energy today hitting stuff with a stick and watching porn.

Not entirely true. It's an exothermic substance, and friction causes it to crystallize.

wait, doesn't exothermic mean it produces heat?

so wouldn't he potentially burn his hand while doing this?

did not know that.
thank you science anon

No problem, just doing my duty. I don't like logging in but I still like making a contribution.

Sodium acetate in a super saturated solution, the touch from his hand causes crystals of sodium acetate to form on his hand, then they grow until all the sodium acetate has fallen out of solution. You know how you make rock candy or those big salt crystals at home? Its really the same thing.

Sodium acetate. It's a fun little exothermic liquid made by combining Baking soda and acetic acid. You can make a cheap but unreliable version at home with pure white 100% vinegar and baking soda. Something like 100 grams of soda per liter of vinegar. You boil the mixture down into a powder then heat it until it turns into a liquid. Then you freeze the liquid for 30 to 40 minutes until it turns into a clear semisolid. It has a low solidifying temperature, so adding heat to the reaction kicks off a counter-reaction that begins to expel heat. It gets really hot and hardens. It's the same stuff that's in sporting heating pads that you can reuse by freezing them. Basically adding kinetic energy causes it to expel all of its heat and harden. Most people call it "hot ice".

Its just super saturation, it could be salt, or sugar, or anything else that dissolves. Its a pretty simple thing, basically you heat up the solvent so it can dissolve more solute, then cool it down and when disturbed the dissolved solute will "fall out" of the solvent and crystallize.

I thought everyone had to learn this in grade 9 science...

Not everyone gave a digestive end product in school. Wanna know the most prominent thing I remember about science class? Fish can control their buoyancy because of an organ called the "swim bladder". That's it. The rest is a blurry haze of "Oh my god this is so boring why isn't the bell ringing".

Not that I'm like that anymore, I think I'd actually enjoy learning about that stuff. But as an immature teenager the only things I cared about were girls and video games. Super saturation and dissolved solvents were pretty low on the priority list.

That's instant ice (basically pure water freezed just a right way)

No it isn't. It has something to do with sodium acetate.
User avatar #12 to #1 - WhiteCrayon (07/13/2014) [-]
Good attempt, but thats not it, someone explained that it has something to do with the solution more consentrated than the liquid or some sciency **** , I can't for the love of me remeber the term. ***** had wikipedia backing his ass.

super saturated maybe? boiling water to make the amount of possible dissolved solids highest, then it cools down to room temp, when it should not be able to hold that many. it stays there for a time but breaks down and falls out of solution when agitated, by hand perhaps.
#27 to #19 - wwttff ONLINE (07/14/2014) [-]
No, its sodium acetate. Which is a solid at room temperature but can only turn solid if it has something it can crystallize off of. So basically, you completely melt it then you cool it and if there is an acceptable crystal formation the acetate aligns to it and crystalizes

Cuz I'm sure not proud of my spelling.
