Learn about gyroscopic forces with this timeless scientific instrument in a reimagined new design. The gyroscope comes with a 30-inch string, a clear plastic sphere which functions as a stand and storage case, as well as 6-page manual with experiments to explore the physics of motion, forces, and gravity. A great affordable, fundamental, and classic scientific device that is perfect for showing physics principles. Make the gyroscope balance on a tabletop, on the included stand, or on a string! The gyroscope is small enough to easily transport and is made of durable materials. Description This timeless scientific instrument has been reimagined in a fresh, new design. Experiment with the gyroscope to learn about the physics of motion, forces, and gravity. See and feel gyroscopic forces in action. Have fun getting your gyroscope to do classic physics tricks like balancing on a tabletop, on a stand, or on a string. Spin the gyroscope inside the included clear plastic sphere and see and feel the forces acting on the sphere. It includes a 3-inch diameter plastic and metal gyroscope, a clear plastic sphere (also functions as a stand and a storage case),a 30-inch string, and an instruction manual. This classic scientific device is essential for anyone interested in physics. It's the perfect size and an affordable choice for use as a stocking stuffer, party favor, or an Easter basket goodie.
