Mistakes,mistakes,mistakes. Like yesterday.. This was the trick : One spectator take a card from a deck. Then his card is going back to the deck. Then its revealed that all the cards are white and the only normal card that is inside is the spectator's card. Ok well known trick with a lot of techniques to do it. I did the trick but... When i put again the card inside the deck i started to tell a small story abou unique decisions that we take as persons. I said "yes you made a unique decision here with your card". Then i asked the girl beside him. "so what do you think that will happen now?". And the girl described all this thing that i did in the next moments and the trick lost its magical moment. Then i asked the spectator "how do you think this happened?. And he describes to me (not 100%) what i did.. After the perfomance i had a self descussion. "How they knew what i done?" After some minutes of sceptical moments, i realise that, there wasn't a problem with the trick. I did the trick (the technique) very well as i wanted. The problem was with my mouth. It was me that i revealed the trick. I tell them what happened and i didnt undestand it that moment...I learn magic from 2005 and last night i did mistakes like a newbie.. Conclusion... The questions "What do you think will happen now,do you know what happened now,do you know how this trick was done.." must be banned...dont ask, let them to question themselves after you do the trick and when you leave the table.. (Why i wrote this? Because i did a mistake and i want people that are new in this kind of art to do not do the same...).Thanks for reading and sorry for my english language..
