: Connect the two metal balls with a rubber band, then twist the rubber band and put the metal ball on the table. The ball will start to rotate in one direction and then in the other. This strange phenomenon is similar to the so-called "pendulum" movement. This paper makes a theoretical and experimental study of this phenomenon, and explores the relevant parameters that affect the motion, such as the type of rubber band, the material of the contact surface, and the size of the metal ball.
