Students can stay cozy and warm indoors while they build a snowman! Insta-Snow powder turns plain water into a realistic, snow-like substance within a few seconds. This snow is actually a superabsorbent polymer, so children will develop an appreciation for polymers and their versatile applications. Polymer snow will dehydrate, but can be re-used by spraying or mixing with water. Great for snowy displays in windows or on tables. Kit includes 0.7 oz. of Insta-Snow powder, snowball molds in 3 sizes (1-1/2", 2" and 3"), plastic snowman accessories, measuring scoop and instructions. Powder makes between 1/2 and 3/4 gallon of snow.
