Thank you for your answers to my question.
I'm familiar with misdirection.
For example, I've been performing Homing Card Plus,
from Card College 2, since 2007 (for 8 years).
In that routine, performer shoves the entire deck in his
pocket right under the nose of the audience.
It's one of the staples in my close-up act.
I also have performed Card under Spectator's Drink
3 times in a row for the same spectator.
However, in the above 2 examples, I misdirect AWAY FROM
the dirty/hot zone.
In the Cooler, both answers to my question say that the misdirection is picking up the card case,
which the deck of cards is sitting on top of.
How is that misdirection?
if I'm directing their attention to the exact spot
that looks suspect?
