Make five colorful, rubbery balls resembling planets in minutes. Using a spherical mold and five colors of polymer granules, cast up to five rubbery planet models. Learn why the balls form and how the elasticity of the polymer material causes them to bounce. A full-color manual guides you through two experiments. These science experiments cover Matter and Its Interactions and Structure and Properties of Matter.
