* Attach a ball to each end of a string and connect the center of the string to a pivot. When the pivot oscillates along the vertical direction, the balls start to collide and oscillate with increasing amplitude. Investigate the phenomenon. | * Attach a ball to each end of a string and connect the center of the string to a pivot.
