It is such a great trick and has become one of my repertories that I perform when I am handed in a
deck of cards on the spot. The greatest part of this trick is that it has massive spectator
interactions. I did this trick in a lecture room and people kept discussing it during the lecture.
It's definitely my reputation maker. And its simplicity is perfect for beginner. The only reason
that it loses one star is because it might be obvious for magicians having a few year's experience.
Anyway, it's perfect for lay people.
