Perpetual Movement Globe

Powered only by room light or sunlight and employing the Earth’s magnetic field as torque, this globe makes a unique gift for anyone interested in the Earth. Ambient energy causes an Earth globe to rotate inside of another clear globe via an internal solar cell that propels a small, magnetic motor. Perfectly safe, clear fluid between the two globes magnifies the inner one, making it appear to be on the surface, and further mystifying the viewer! No power cords or batteries are needed. Includes a three-pronged display (or use the base of your choice). 4½" diameter. China.
