The eight-inch Anderson Antique Floating Globe uses computer-controlled levitation to keep the earth afloat. This high-tech electronic magnetic system defies gravity and will surely amaze and delight your friends and family. When the globe is on, it floats perfectly between the base and upper frame. A built-in mini computer adjusts the magnetic field approximately 16,000 times per second to ensure perfect placement of the globe. When the globe is off a permanent magnet in the base keeps the globe secured to the frame. The Anderson Antique Floating Globe features detailed cartography that features over 3,000 named landmarks. This unit requires an active 110V/60HZ outlet to levitate.
