This is Penn and Teller, performing a trick*. First they perform it, then they show you how it’s done. Watch the video again, and it doesn’t feel magical anymore. Yet this is how Penn and Teller must feel about all their tricks. It’s not just the second time they’ve seen it – it’s the thousandth time they’ve practiced it. For a magician to create magic for someone else, he must destroy it for himself. This is the artist’s paradox.
