Another edit:I took out my annoying voice talking and the music and added annotations as well as a beautiful rendition of Chopin's Raindrop Prelude Op. 28 No. 15.
Edit: I got 1st place in my science fair for this. :D
What is sodium acetate? It is an acetic acid with sodium bicarbonate mixture, usually found in salt and vinegar chips. Not only that, but it can also crystallize at an astonishing 12 cm/sec or so. You can make your own sodium acetate at home. To crystallize it, you need to touch a supersaturated form of sodium acetate with sodium acetate trihydrate (which is in other words the crystallized form). This video will show you how to make your own supersaturated form of sodium acetate for your own personal use.

Why filter the solution? Because not all vinegars are the same. With this method, you remove the impurities of the vinegar. I've made it successfully work with three different types of vinegars, including palm vinegar for you Filipinos out there, heheh.

Ingredients you'll need:
Vinegar
Baking soda
Filter carbon (bought at Petco in the fish section)
coffee filter
some ice

Depending on how much vinegar you're using, the end result amount will obviously be different. You can assume that the consequence will be 1/10 of the original amount.

Caution: DO NOT TOUCH THE SUPERSATURATED FORM OF SODIUM ACETATE WITH YOUR HANDS. IT WILL CRYSTALLIZE ON YOUR SKIN, AND THOUGH IT IS EASY TO WASH OFF, YOU'LL BE BURNED BY THE AMOUNT OF EXCESS ENERGY RELEASED. ALSO, DO NOT EAT IT, PLEASE.
