“Happy” and “Unhappy” Balls

Avg. Ratings: 5.0 (1 Review)

Use to Demonstrate Elastic Force

  • The two balls come with instructions
Although both balls are identical in shape, the “happy” ball rebounds very well while the “unhappy” ball does not. Several experiments involving the simple bounce and roll of these balls demonstrate repulsion and inelasticity.

Caution: WARNING: CHOKING HAZARD–This toy is a small ball. Not for children under 3 yrs.
