One cap of anionic polyacrylamide powder (snow) is placed in a 4 oz. portion cup. Water is added to the portion cup until it is completely full. As the snow absorbs the water it also binds with the air and creates a fluffy, white, powdery by-product that resembles freshly fallen snow. This chemical is reusable: let it dry out, store it, and pull it out again next year.
