To play this you will need a small stone, a bigger stone, a thick roll of paper (which can be made by with layers of paper), mouse and an elephant made of paper.
Take a string about 2 feet long. At one end of the string tie the small stone. Stick or tie the mouse to the stone.
Put the string into the roll of paper. At the other end of the string tie the bigger stone and stick the elephant. Hold the roll of paper and move your hand to rotate the small stone. Who is pulling whom? You will be surprised! The mouse lifts the elephant! How did this magic happen?
