My first impression of the basic technique and the way it was used in routines, was that it was "too
magical". In other words, you didn't leave room for the spectator to come to any other conclusion,
other than the fact you must've pulled off a very deceptive switch.
So my fear was that
instead of getting a "How did you do that?" reaction, I'd get a "When did you switch it?" reaction.
As it turns out, I was completely wrong. Maybe because the finish is so disorienting, the spectator
simply can't process it right away. Maybe the next day they're able to deconstruct it, but by then,
I'm long gone.
So yes, I'd recommend this very highly. Aside from the great reactions,
it's really very easy to do. And whether you're laughing with him or at him, Jay's tutoring is
always fun to watch.
