Question

To play this you need a small stone, a bigger stone, and a thick roll of paper (which can be made by 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?

Answer 1

Hint :Collect all the apparatus mentioned in the question, arrange in the mentioned way and follow the procedure. Record the observations of your experiment. The string with stones on both ends moves in a circle and behaves accordingly.

Complete Step By Step Answer:
Collect all the apparatus mentioned in the question. This includes a thread of about 2 feet length, a thick roll of paper, a small stone, a bigger stone, a mouse made of paper, and an elephant made of paper. Tie the small stone to the end of the string. 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.
After following this procedure, record your observations.
You will see that the bigger stone is pulled upwards by the smaller stone as we rotate it. Or in other words, the mouse is pulling the elephant. This might sound impossible but is not.
When we rotate the stone, it creates a whirl, due to which the bigger stone is pulled up. The stone is constantly experiencing a force in a direction perpendicular to the direction of thread at that moment, and also in a direction parallel to the thread away from the stone and a tension also develops in the string due to this kind of motion.
The resultant of all these forces acts in a way that the bigger stone is pulled up.

Note :
Make sure the stones are tied strongly and will not cut loose when the apparatus is rotated. Otherwise, it may hurt you or other people around you or even break delicate things around you. Precautions should always be taken when performing any experiment otherwise, it may end in serious injuries.
