HoverDisk

Indoors or out, the hoverdisk floats on a cushion of air generated by its high-speed motor to offer an interactive lesson in air pressure mechanics.

Demonstrating the same scientific principles used by modern hovercraft, it miraculously glides and zips across low-pile carpets and hard surfaces like sidewalks and floors at the slightest touch. Soft bumpers protect people and possessions, and a rechargeable power pack provides 30 minutes of fun per charge.

Includes AC adapter for easy recharging. 7 1/2'' diameter. For ages 7 and up.

The HoverDisk can purchased online at National Geographic.
