Great liitle trick. Its good that they make the gimmick for you. I perform the Wilson change by just
saying "look, I only got one single dollar" as I show it, then I say "I need something better, like
a CREDIT card" in a almost kid getting excited happy tone in my voice. Then I just display the card
and put it in my pocket and get good reactions. They were Entertained. Buy it, 5 minute practice it,
wallet it, then wow people with it.
Oh, I perform this for a first time spectator. And the
person was literally frozen in Awe after the trick.
