A must have for every physics teacher. Why do bicycles stand upright? Dramatically demonstrate angular momentum with our Bike Wheel Gyroscope. Spin this bicycle wheel, hold the handles, and try to change its axis of rotation.  The faster it spins, the harder it is to tip over!  Stand on our Rotating Platform (P3-3510) to experiment with gyroscopic precession and learn how satellites steer.
