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.
