New. Unused. Unopened. Out of print. Rare item. This is a 4-Dimensional Trunk. American magic inventor J.C. Doty became famous for creating a magic trick where he produced a bowling ball, much larger than itself, from an ordinary trunk. This "4-Dimensional Trunk" was created to capture the impressive impact of that magic trick in a smaller, more accessible format. A dummy ball is included so you can start right away, but ◎ You can also use real golf balls ◎ Performing this in front of golfers will be especially effective and well-received.
