Polymer snow is a super absorbent product that expands 40 times in volume when water is added, creating a soft, dust-free particle slightly larger than the powder. This particle is soft, slippery and ‘dry’ to the touch; it is ideal for pouring and is therefore good to simulate avalanches. Never use the raw powder as snow, always add water. Be careful clearing Polymer away as it will block sinks and drains. To remove any blockage just add salt. 2.2 lbs (1 kg) of powder will make 0.1 cubic meter of snow (10 sq m or 107.64 sq feet x 10 mm or .4 inches deep).
