Just imagine! - You borrow a coin from a member of your audience and say that you can actually vanish small items by using the "Power of the Mind".
You then clearly place the coin onto the palm of your left hand, and close your fist with the coin clearly still in the palm.
You now turn your clenched fist over and give a little rub on the back of your left hend with the forefinger of your right hand, as you say, -
"It just takes a little concentration." . . . . . .
There's a great Finale that you can easily use to get a real burst of applause and then a lot of Laughter .... Try it and see for yourself...
