The STEM LABZ gyroscope with a modern design is a timeless scientific instrument. Use the gyroscope to learn more about the physics of motion, forces and gravity. Have fun watching the gyroscope perform classic physics tricks. Try to make it balance on a flat surface, stand or string. A small but very fun tool that can be used every day to see the laws of physics in practice. While playing, children will develop critical thinking and concentration. Approximate diameter: 7.6 cm.
