Levitating Top Demonstration
Overview:
Gyroscopic motion, like that of a spinning top, creates a force that can be used to stabilize an object. Magnets can be used to either attract other magnets or repel them. When the forces of gyroscopic motion, magnetic repulsion, and gravity are all balanced correctly object can be made to levitate. The amazing process of levitation is displayed excellently using a Levitron top. There are no camera tricks, mirrors or wires used to make our top "float". As hundreds of our visitors can tell you this is just an amazing sight to see. Note: This video does not include audio.
