> Penn & Teller have made a career out of showing how tricks are done No they haven't. P&T don't really show how tricks are done. They especially don't reveal big secrets used by other magicians. The notion that they're doing something transgressive that makes other magicians dislike them is just a schtick they came up with for publicity purposes. When P&T do "reveals" they are usually mock reveals - revealing a technique that they're not actually using which often was invented specifically for the purpose of being revealed. Or they're "revealing" something that everybody already knows which in no way detracts from the enjoyment of the trick. And sometimes they're just riffing on the psychology of magic, showing us how even when you're trying hard not to be fooled you can still fool yourself. (The clear Cups And Balls might be an exception to this general rule. That's the only one I can think of that more-or-less fits your description.)
