A classic of kidshow magic. Show a frame made with two doors in the front and two in the back. Also show a cute little bunny-rabbit. Place the bunny into his house, and close the door. Now, if the kids see him run across the street to the other house, they are to tell you right away. Needless to say, the rabbit immediately runs across to the other house. And, the kids scream that they saw him go. When you open the doors, he's run back to his own house. So, you open the door to his house, and he runs back across the street to the other house. Back and forth he goes. The kids always see him run, but you never catch him. He even peeks out from behind the house. The kids go nuts. Finally, you open all four doors, and the rabbit has vanished. He ends up hanging on your back.
