The basic effect described is just the beginning of what this set amazingly can do without sleight of hand. Three beautiful spun cups are shown to be solid and empty. There are no trap doors or gimmicks of any kind. Three balls (colors may vary) are displayed in front of the cups. One ball is placed on the center cup and covered with the other 2 cups. Give the cups a tap and the stack is lifted to find the ball has MELTED through the cups and landed on the table! They will not believe it so you do it again. You lay out all the cups covering the ball in the center and put one cup on it and then a ball and then a cup. Now you tap TWO times and when the stack is lifted, THE SECOND BALL HAS PENETRATED THE CUPS to join the ball on the table. WOW - solid through solid WITHOUT sleight of hand! But that's not all. You repeat it with the third ball penetrating the cups again! There are many more magic things you can do with the cups and balls. Specially designed cups are UNGIMMICKED and may be handed out for examination. Each cup measures approximately 2.25" tall and 2" in diameter. For the advanced effects see one of our great books or DVDs on the cups and balls.
