This remarkable material is a form of polyacrylamide, capable of absorbing
many times its own weight in water and expands rapidly when wet to form a
snow-like mass.
Mix with water to make your own snow as seen on TV and film sets
Ideal for science investigations and as the raw material for snow machines that pupils design
