| A rotational force exerts a gyroscopic or centrifugal force. This force keeps the toy upright. As the force reduces, the effect lessens and the toy eventually falls over. With a humming top a downward motion is transferred to a circular motion. The main stem is depressed and using a screw creates a circular motion. | |||||||||||
