Sometimes, I just have to share how I feel for others to read and possibly disagree with. This effect seems like one of those things magicians will go (radio) ga ga over and will fall flat when performed for real people.
It might be the slow tedious seriousness of the demo video, but it bores the hell out of me. The only way to sell this to real people would be to let them frisk you before and after the effect. How many of us don't have cards and fake limbs and jello in their pockets? Seems impractical to me.
Often I look at stuff like this and ask myself, "Do I have something just as strong, if not stronger in my repertoire already?
The answer is usually yes.
