Gyroscope STEM Kit This timeless scientific instrument has been reimagined in a new design. Experiment with the gyroscope to learn more about the physics of motion, forces and gravity. Learn about gyroscopic forces, see and feel them in action. Practice classic physics tricks by balancing the gyroscope on a table, on a stand and on a string. Rotate the gyroscope inside the included clear plastic sphere and see and feel the forces acting on the sphere, which functions as a storage box for your gyroscope. The gyroscope has a diameter of 7.5 cm and is made of plastic and metal. Contains gyroscope, a clear plastic sphere (also functions as a stand and storage box), a 75 cm string and instruction manual. Recommended age: +8 years. WARNING: Not suitable for children under 8 years, contains small parts, choking hazard, contains long string, strangulation hazard. Adult supervision is recommended during play. Read instructions before use, follow them and keep for reference. Made in China for Thames & Kosmos, England.
