Dropper Poppers are more than just half of a rubber ball. Made only in Australia, this incredible device seemingly defies the laws of physics by bouncing higher than where you dropped it from! Unlike some similar products, this one requires a small amount of "activation energy" to work. It is molded into a very special shape that allows it to store elastic potential energy and then convert it to kinetic energy with a POP when dropped from a low height (i.e. a small amount of activation energy is applied.) Drop it from a height of about 4 feet and it will jump to 8 feet or more. Dropper Poppers make a great "activation energy" demonstration. An engaging activity for any Physics or Chemistry Class!

Try This:
Have your students experience the difference between gravitational and elastic potential energy. Invert a Dropper Popper, place a ping pong ball inside the cavity, and drop the Popper onto a hard surface with the ping pong ball on top... Be sure to wear goggles and have a high ceiling, or better yet, no ceiling at all! Estimate how high the ball travels. Change the height of the drop and determine if the height the ping pong ball travels is based more on gravitational or elastic potential energy.

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.

Choositz Decision Balls

Dropped onto a hard surface, one ball bounces high while the other hits the floor and stops immediately.

String Launcher

Watch it seem to defy gravity as it floats, crawls, curls and even walks along a flat surface.
