Magic Tricks

Great trick. After performing it a few times, I've adjusted two things.

The double prediction makes little sense. If I predict with a card, why do I make a second, identical prediction with the bill? And yet the card prediction is necessary, because it provides time misdirection. (I.e., it would make no sense to mark the selection with the bill and then immediately remove the portion of the deck above the bill. "What is that all about?")

So I put the prediction card in my pocket and produce it only after the card has been selected. It's a weak prediction. ("How many cards did he have in that pocket?") Perhaps sensing audience dissatisfaction, I show the prediction on the bill. That prediction has real punch, a punch somehow enhanced by the previous lame one. Two predictions now make sense. It's a sort of "magician in trouble" reveal.

As someone else mentioned, there is a slight angle problem. It may be slight, but it was noticed the first time I performed it. (We were all seated at a table and the participating spectator took her time before calling stop. Both of these things enhance the problem.) Now, if all are seated, as I'm moving the bill and cards to the side, I rotate them about 90 decrees and, still touching only the bill, I raise the near end of it slightly so that the deck bevels slightly toward the spectators. This does away with 95% of the angle problem, and it looks natural enough -- it's natural that if you handle bill and cards in this fashion, the cards are not going to arrive on the table all squared up.
