Fun stuff! Great for chemistry demonstrations. This is the kind that makes a solid glop, not snow.
Put about 6 grams of sodium polyacrylate in a 400 mL beaker, then pour about 300 mL of water (from a decent height to facilitate mixing) into the powder. Distilled water is tops and you can use less, but tap works as well. In about a minute, you have a goo that will cling to an upside down beaker like a tween to her iPhone. Reverse the effect by adding a few grams of sodium chloride (salt) and agitating (stirring) until you see a structure change (common cold booger to watery allergy snots).
I keep a baggie in my purse when I go to bars. My friends are sick of chemistry, and really sick of solid drinks. I still think it's hilarious. Be sure to dispose of this stuff properly, i.e. not in YOUR drains. Your chemistry-hating friends' drains are fair game.

I just have to say amazing. I used more than I should have being skeptical: it kept absorbing the more liquid I put into it. Please use the right proportions so you do not waste it. Many uses for this product
