Product Description
Foam Gnomes by Bryce Hixson
A very dramatic and entertaining demonstration of a chemical change. Half ounces of Poly A and Poly B are mixed together in a plastic cup. As the two chemicals react, a large pile of hot foam rises out of the cup and quickly hardens. The kids can see and feel, first hand, indicators of a chemical change: evolution of a gas, release of heat, and a color change.
