Card magic I'm going to share with you some magician's secrets, but first please just say stop whenever you like.. ( I riffle the cards ) RIght here? are you sure? Ok, please take your card, remember it and show everybody, I will not look ( spectator showing the card ) and again, just say stop whenever you like .. ( I'm putting piles of cards on the table ) please put you card here ... and now it's lost in the deck, right? fair, isn't it? ... Have you ever heard about marked deck? I will teach you how to spot the marking, but please do not tell anyone, promise? Ok, fine :) I'm afraid that the lighting here is not the best ... the mark should looks like .... THIS! ( showing blue card in the middle of red deck ) Can you see it? really? nice! and what was the name of your card? ( flipping the card - spectator go wild ) Wow, splendid! ( putting the card aside ) I'm going to break another magician rule : "Never do a trick twice". So, do you want to see it again? :) Please say stop, remember your card, and now, in the second time, your card will be the odd one in the deck, now you know how to spot the marking... ( spreading the deck on the table, can't find the odd card ) oh, s**t, hmmmm, What was the name of your card? sometimes, even I can't understand this ... ( taking one step back from the table ) please turn the blue card ... ( the first card has changed to the second one! ) Please keep the secret with you.
