Sodium polyacrylate is a synthetic polymer made up of one repeating formula, linked together in a long flexible chain. It is capable of holding up to 400-500 times its weight in water. It has a variety of industrial uses ranging from laundry detergent and fake snow to baby diapers and even a maximum absorbent garment used by NASA! It starts out as a white powder substance, and when mixed with water becomes a clear gel material. However, it can be liquefied by adding salt to the gel material. It can also be dried out and and reused to make another batch of gel - or fake snow - by adding water to it again. Anyone can buy it at a pretty low cost online. And it doesn't take much powder to get a pile of gel. Check it out! It's pretty cool! >>By the way...you can see a demonstration of its use on youtube.
