Explore the science of super-absorbent polymers with an amazing, non-toxic powder that erupts into an amazingly realistic drift of "snow" when you add water. Packed into a small amount of the dry powder is an amazing reaction. Insta-Snow is a compact, super-absorbent polymer that quickly (in seconds) "drinks" up lots of water and "erupts" instantly, expanding to 100 times its original size. The reaction is very fast and very visual. Kids and adults of all ages will love it. The Test Tube of Insta-Snow contains 10 grams of snow powder and makes approximately two cups of faux snow. Use the activity guide to learn the science behind the erupting snow.
