The Wacky World of Superabsorbent Polymers - Chemical Demonstration Kit
By: Steve Spangler, Regis University, Denver, CO
Item #: AP6303
The Wacky World of Superabsorbent Polymers Chemistry Demonstration Kit uses a fun approach to teach students about polymers, osmosis, and cross-linking. Use distilled water, an "empty" cup, and a beaker in this simple, informative display.
This item can only be shipped to schools, museums and science centers
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.Enough materials are included to perform this demonstration seven times.
Concepts: Polymers, osmosis, cross-linking.
Time Required: 10 minutes
Chemicals Provided: Sodium polyacrylate, PolySnow™.
