I did it to ten different sets of folks. Mostly, it seemed they got tired of the repetition. I'd
made the point of the cards being clearly mixed early on and they got it. They didn't have a
dynamite final reaction. Too long a routine, and especially in the middle of a five routine set
(#3). Hide a card, find a card. I expected it to have a greater impact, and it was just average. The
premise is good, the impossibility is fine. So, it's worth trying. Hope you have better results than
I.
