Abstract
A battery operated gyroscopic entertainment device is powered from a mating cradle, or from a battery supply within the device. The device includes an egg-shaped housing in which is disposed a high speed DC motor whose motor shaft preferably extends from each end of the motor. A hub member is attached to each shaft end, and a weighted belt is attached to each hub member. A central portion of the motor housing is fixedly attached to the device housing such that upon application of operating potential to the motor, the motor shaft, and the weighted hub members rotate at high speed, which imparts a gyroscopic action to the device. A cradle may be provided containing a power source, with power connections that mate to the device housing when the housing is placed within the cradle.
