These are the largest "Happy-Sad" balls we have seen! They are 1-1/2" in diameter! These two black rubber balls appear identical, but have extremely different physical properties. Dropped onto a hard surface, one ball bounces high while the other hits the floor and stops immediately. Show students that some properties cannot be observed without experimentation. Set includes two balls (one 'yes' and one 'no').

Astro-Blaster Multiple Collision Accelerator

When the apparatus is dropped straight downward onto a hard surface, the top ball can rebound to a height equal to five times the original drop.

Bouncing Animal Spring Demos

Hang them from a hook, give them a pull, and you have a wonderful demonstration of oscillation.

Dropper Popper

This incredible device seemingly defies the laws of physics by bouncing higher than where you dropped it from!
