  2. You could use cold reading to get the card from the audience. The red/black choice you could twist and say the audience is now ruling out cards. High low choices could be predictable I think.

  3. All I needed to know is that this trick fooled Penn and Teller. Awesome.

  4. Very well done. I'm impressed.

    It seems certain that cold reading isn't really involved for two reasons. (1) He asks "Which one do you want" regarding color before a choice is made and never reverses the sense (selection/elimination) of any choice.

    (2) Three binary choices is not enough to uniquely identify one card out of 52. Ultimately the final choice of [7,8,9,J,Q,K] is free unless he somehow manages to get the ball to his confederates each time. Otherwise it looks really fishy to say "OK, you picked the seven we eliminated that one. Pass the ball to another person and have them choose from the remaining ones." That could occur five times before someone chose the nine which makes for a really sloppy trick.

    Personally some of my favorite magic is by René Lavand, a man with no right hand.

    Here he is performing a simple trick that feels very "magical".

  5. There is a bit of a force. As I noticed (and confirmed based on a website that reviewed the kit), the audience can't pick the Ace.

    I think I've figured it out, and it really just involves one deck of preprinted cards.... no hidden inkjet printer or accomplice.

  7. The elimination of the Ace is necessary to produce twelve, rather than thirteen, possibilities. This enables him to reverse and sort the cards to produce the writing on the edge by manipulating the pre-sorted pattern. He can yield the name of any card. This would be far more difficult with an odd number of cards in a suit, if not impossible.

  8. re elimination of the ace, I think you're exactly right. I hadn't thought of that aspect of it. good point.
