This is a great trick which Lonnie Chevrie also taught in his Penguin lecture, Lonnie Chevrie Live!
It's easy to learn, genuinely impromptu, and can be done with any borrowed bill. It makes a good
follow-up to a pen-through-bill or pencil-through-bill effect, or to Chevrie's bill-through-bill
effect "Clean Thru." All of Chevrie's material is very practical. The only limitation of Clear
Through is that you can't have people directly to your side or behind you when you perform. However,
I have never found this a problem. As long as the spectators are standing in front of you (or even
to your side but a little in front) the crucial move is invisible.
