I have performed this six times in a parlor type environment. Each time I have presented this the
audience was blown away. In the words of Harry Lorayne, “it’s a grasper”.
Things you
should consider: this routine requires a force and a top change is required. However the
missdirection is so strong at the moment you execute the top change you could exchange the card in
question for a one with a different colored back without being noticed by the audience. So if your
top change sucks it’s still OK :-)
