Seeing the Jack of Hearts on My Arm

The first fail has to do with me describing on that video how it is that i get people to believe what it is they're seeing, even though it's really not what they're seeing. And then about an hour later into the show, at the end of the presentation, i do a trick that fails, and i manage to make it work by doing exactly what it was i told the audience that i was doing before. So it seems that this technique can be effective even after i 've already told the audience about the technique and how it is performed. In retrospect, it was a very interesting psychological experiment, and one which i think shows how deeply this idea goes.
