Bounce No Bounce Balls by Steve Spangler

Looks can be deceiving! These two black rubber balls look and feel identical—but when you try to bounce them, you’ll quickly discover their surprising secret.

One ball rebounds with lively energy, while the other drops flat to the ground without a bounce. It’s not a trick—the balls are made from two different types of rubber. One is elastic and full of spring, while the other is inelastic and behaves more like clay.

This classic science and magic effect is both entertaining and educational, making it a favorite for teachers, magicians, and curious minds alike. Use them to demonstrate the surprising differences between potential and kinetic energy, or simply to amaze friends and family.
