Swing a ball and watch the swing balls move by the kinetic energy. The toy will always keep moving for a few minutes due to air resistance and friction. It swings and slows down when time elapsed and finally stopped. Ideal for relaxation and anxiety as it creates a calming motion. Safe for children to use.
