Everything needed to uncover the secret of movie making snow comes in this box. Just add water to create an erupting blizzard of snow any time or anywhere. 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.
