Maxello Magic

Show a big card on which there are four spots to the audience. Then, move your empty hand in the air and put it on the card. When you remove your hand from the card, the audience will see that the round spots have increased and become five.

Again, you put your hand on the card, and this time the spots have become six. Keep on doing the same action till the spots would increase to eight. When they become eight spots, this time, by putting your hand on the card, the spots will be decreased. It means they will be disappeared till the first four round spots return to their original places.
