Gyroscopes demonstrate an important physical principle of the conservation of angular momentum. This principle is used in bicycles, levitating tops, satelites and navigation systems of airplanes and space shuttles. This is a high-quality TEDCO gyroscope that comes with a stand and a starting string, and is packaged in a transparent plastic box. Excellent as a party favor or stocking stuffer.
