Zeebeez Rockets

Convert potential energy into kinetic fun when you drop the surprisingly springy Zeebeez.

This simple, pocket-sized plaything shoots up to six feet in the air with no more than a spin and a drop. To make it pop, just turn the rubber half-sphere inside out and twirl it slightly while you release. The impact from the surface returns the toy to its original shape, causing it to spring into the air as if the sidewalk were a bounce house.

The scientific demonstration is a blast to replicate again and again, surprising friends every time.
