Bouncing Planets

Description

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.

  • Thames and Kosmos makes great kits and the manuals are so full of great science information.  They are truly a step above other science kits!

    Thames & Kosmos was founded in 2001 by a science museum director and her son, who saw the great need and demand for better science education materials — resources for parents and their children that are more engaging, more effective, more relevant, and more fun.
