Product Details

Pour distilled water into an “empty” cup and the water solidifies into a gel. In another beaker add a small amount of powder, pour in distilled water and see an avalanche of fresh powdered “snow.” These remarkable sodium polyacrylate polymers have many water absorbing applications, including indoor artificial snow! Teacher Demonstration Notes included.

Concepts: Polymers, osmosis, cross-linking.
Time Required: 10 minutes
Chemicals Provided: Sodium polyacrylate, PolySnow™.
