Show a half dollar coin in your left hand; take the coin with your right hand at the same time that close your left hand and put the coin in your pocket. Open your left hand and the half dollar coin will be there again. Repeat the movement and the coin will be in your left hand again. Now, take the coin again and put it in your pocket, open you left hand and a jumbo coin will appear. If you prefer candy, it could appear in place of a jumbo coin.
