I was thinking about Penn and Teller’s recent show “Fool Us”, where they get a chance to watch a trick once, from one angle, in the audience; and then they have to work out exactly how it’s done. i didn’t watch many but they had a pretty good success rate. Are there any tricks though, that even after repeat viewings professional magicians cannot work out.
Not necessarily replicate, perhaps it does require a lithe body or an amazing memory etc., just figure out. For these purposes I’d disallow any trick that has never been performed in front of an audience or requires a volunteer who is not explicitly one of the magician’s assistants, unless it has been performed with a volunteer who would be unimpeachably honest.
