I performed this trick for a teenager recently and he only said two words (over and over) "That's
impossible" and then walked away.
Effects this good shouldn't be self-working. It's almost
unfair. Of course there are triumph routines (like Oz's great one, "Triumph") but they require
difficult sleights and the audience can often tell you are working hard for the result you are
giving them.
Cheek to Cheek just works and the fact that you can perform it with such a
casualness adds to the effect. I often use this trick when I have someone giving me a hard time.
Rather than pulling out some elaborate trick that makes it look like I am trying to impress him/her,
I just pull out Cheek to Cheek and let it work for me.
If you haven't got it, buy it. If
you've got it - buy another copy just to ensure that someone else can't. This is a secret that I
don't want to share.
