Explore the science of superabsorbent 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, superabsorbent 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 jar of Insta-Snow ® contains 100 grams of snow powder and makes approximately two gallons of faux snow. Use the activity guide to learn the science behind the erupting snow.
