I like this effect because the spectators don't know what's coming. It also has the "oops, the
magician screwed up" moment that is always good for laughs. In fact, I would play up that aspect
even harder. Keep cutting trying to find the spectator's card, and act more and more frustrated.
This gives you even more time and misdirection with which to perform the mercury fold.
One
thing about the demo video... I would NEVER say, "Look, my hand is empty" and then show just one
hand... because as soon as you do that, the spectator's eyes are immediately drawn to the OTHER
hand, which is clenched suspiciously at your side. Very bad.
Aside from the possibility of
making performance errors like that, the trick is easy to perform. The mercury fold is not
difficult because it needs to be done during misdirection. It's not a move you're trying to perform
to fool anyone. What takes practice is working out the timing of WHEN to do it, moreso than HOW to
do it. The only other move you need to do is controlling the selected card, which is well explained
and shouldn't be a problem.
