Rainbow Light Effects Gyro Wheel
Demonstrate the conversion of potential energy to kinetic energy and back again. The colorful wheel has a hidden LED light inside. As soon as the magnetic edges of the wheel touch the metal rails, the LED lights up - a perfect demo of open and closed circuits! Simply tip the rail to begin the spinning motion. Turn the handle 90 degrees to spin the gyroscope horizontally. Once it is spinning fast enough, fling it off the rail, onto the floor, and marvel at the amazing light effects!
