The Gravitron seems to defy gravity allowing even young kids to perform many tricks like balancing it on a finger or spinning it on a kite string.
Hours of fun while learning about the scientific principles of Newton’s laws of motion, gyroscopic balance and center of gravity. Includes T-handle cord, pedestal and instructions.
Chicago’s Museum of Science and Industry choose Gravitron to be the subject of their exhibit ToyMaker 3000: An Adventure in Automation. Be sure to visit and see the exhibit for yourself.
