The Spin Doctor seems simple enough but the effect is quite cool!
One inner multi-colored LED ball sits inside a larger hollow plastic ball. Move the outer ball around in your hand and the inner LED ball revolves and spins around in unpredictable fast orbits of bright light that reflect off the shiny bottom of the outer ball. Based on the traditional Chinese stress-relieving balls, the Spin Doctor is a prescription for hours of fun!
Includes a storage stand and replaceable batteries (3xAG3). The outer ball is approx. 4″ diameter.
