"cups and balls" 的定义和意义

What is "cups and balls"?

Cups and balls is a classic magic trick where the magician manipulates three cups and three balls in a series of seemingly impossible movements. The trick typically involves the magician placing the balls under the cups and then making them appear to vanish, reappear, or move from one cup to another. Using sleight of hand, misdirection, and carefully timed movements, the magician creates the illusion of the balls magically traveling between the cups or disappearing entirely. This timeless routine showcases the magician's skill in creating surprising effects and maintaining audience engagement through a combination of technique and theatrical presentation.
