魔术师向观众借一枚硬币。魔术师拿着硬币在手上，每一步都绝对干净, 它渐渐弯曲！并且硬币是可以签字的，弯曲的硬币下落到观众的手里。 并让观众检查是他签字过的原始的硬币，没有被替换过。
The Magician approaches an unknowing spectator and asks, "Do you have a quarter on you today, Ma'am?" The spectator proceeds to look for change in her pocket. The Magician then prompts, "Could you please sign the coin for me before I take it from you." (The coin does not need to be signed, but it adds to the effect's finale.) At this point, the Magician takes the coin, holding it in view of the spectator, and says, "I'm going to try something here ... You know what? You may be able to do the same as I do. Do you have another quarter?" The spectator reaches into her pocket and retrieves another coin. The Magician, holds the signed, borrowed coin at the fingertips, and begins to rub the coin, saying, "Rub your coin like me. Can you see mine starting to bend?" The Magician finishes showing the bent coin, and immediately gives the coin to the spectator as a souvenir. The coin can now be fully examined.
