This is a pocket sized version of the famous Bowling-Ball-from-Attache-Case trick!
The idea is simple- you produce an item from this flat case, an item that is OBVIOUSLY much larger than the case! How is that possible??
Your spectators will be truly startled when you show this small FLAT case, open it, and take out a full size ROUND golf ball. Or a small flower. Or coin after coin after coin, until you have removed a pile of coins much too large to have fit inside the case.
This is a real mystery puzzler with great comedy potential!
Best of all- IT'S EASY! If you can hold the case in your hand, you can do the trick!
This effect is also known as Tenyo Four Dimensional Trunk.
Use this case to produce your business card. It is about the size of a business card case, so you can open it as if to take out a business card. Instead, begin removing larger items, one after another, until you finally produce your business card.
Use this case to introduce the first golf ball for a Multiplying Golf Balls routine. Take the first golf ball out of this case, then proceed to multiply the balls in your hand.
