"detachable thumb"的定义和意义

What is a "detachable thumb"?

A detachable thumb is a magic prop used to create the illusion that a magician's thumb can be removed or detached from their hand. The prop typically consists of a specially designed thumb cover or gimmick that fits over the magician's real thumb and can be removed or repositioned in a way that appears to make the thumb disappear or come off. During the trick, the magician can perform various actions, such as showing the thumb as missing or reattaching it in a dramatic fashion. This effect relies on precise handling and the clever design of the prop to create a convincing and surprising illusion for the audience.
