The word “hot” doesn’t usually come to mind when you think of ice, yet this experiment shows you how to easily transform a liquid into a solid with just a touch of your finger.
I think I might just get me some NaCH2COOH (sodium acetate).
For this experiment the only materials you really need are 500 grams of sodium acetate, water and a pan. According to the author of the video, this can all be obtained for less than $25 USD. From there, all that’s left is to super-saturate the solution and let it cool.
Presto! When the liquid comes in contact with your skin, it will instantly heat up and turn into a solid block of “hot ice.” The video suggests that a fun thing to do with solution would be to make sculptures, but I happen to think mixing it in a toilet bowl would make an even more fun prank.
Whatever you do, just don’t eat it.
