Giant Chinese Coin Threading by Joker

Effect:The magician shows a Jumbo Chinese Coin to the audience, through which he threads a rope. He explains that that is why the ancient Chinese coins had holes in the middle. He loops the rope again through the hole in the middle of the coin. He pulls the rope, holding it by its end, to show that the coin is securely attached. The magician makes a quick movement and the coin comes free from the rope!
