The Cups & Balls is the oldest and most famous trick in magic. The performer shows three cups to be empty, and places them on the table. Giving one cup a tap with his wand, he lifts it to find a small ball underneath. The ball disappears only to re-appear under another cup! The ball is replaced under the cup, but a magic "tap" causes it to vanish and appear under a totally different cup. Another ball is discovered and vanished and then another. Upon lifting the last cup, all three balls are found beneath it. Finally, the cups are all lifted to find completely different, large items under the cups, such as an onion, lemon, and potato! Many variations of routines are possible and available in standard books on magic. These aluminum cups are red, blue, and yellow with a beautiful diamond design. They are (approx.) 2 1/2 inches at the mouth, 1 1/2 inches at the bottom, and 3 inches in height. Exactly the right size for easy and efficient handling, with a concave bottom to hold balls. Perfecting and performing this trick shows everyone that you're a magician!
