I saw David Blaine live on May 24, and he preformed a trick where he sewed his mouth shut, had a spectator take a card, rip the card, then magically have it teleport into his mouth and it lined up exactly. I have a feeling this came with a force and possibly a careful and practiced rip, but I would think that he didn’t have that much set up. Also, later in the show he has a woman pick a handful of puzzle pieces from a jar that was mixed with tons of different pieces, and somehow she narrows it down herself and it fits perfectly into a maps of the US and the piece, which was part of California, fit exactly to where i saw the show, in Hollywood. I have some vague ideas about how these tricks were done, but need help with anyone who would be willing to. I am a very curious and thoughtful 14 year old, and can’t seem to smooth down the minute details of these 2 tricks.
