Or what about placing two glasses mouth down on an unprepared book and having them stick to it like magic. The glasses and book can both be examined.
With this set of gimmicks, you'll also be able to turn a glass full of water upside down without fear of spilling it.
The Anti-Gravity Trio comes complete with all gimmicks necessary to perform these incredible tricks, and detailed, professional instructions.
