Description

A fun, interactive demonstration. One ball bounces high and the other one does not.

  • Set of two black rubber balls, each 1-3/8 in. in diameter, appear to be identical in terms of appearance and mass but are manufactured from different types of rubber
  • When dropped on a hard surface from an equal height, the happy ball bounces high and the sad ball barely bounces at all
  • The happy ball also rolls faster than the sad ball
  • Provides an interesting and memorable demonstration for studying elasticity, kinetic energy, and polymer composition
