aka: Physics Numchuck or Whirligig
Two balls are attached to a string through a tube. The heavier ball can be held up by spinning the lighter ball in a horizontal circle. The radius can be varied, and more weight can be attached to the hanging ball if needed.
What are the action/reaction forces acting on the spinning ball and the hanging ball?
