The Hole Glass By Paul Andrich
Four jaw dropping penetrations.
A glass.
Four coins.
One at a time the coins penetrate the bottom of the glass. The final coin going through in a stunning climax.
Beautiful to watch, fun to do.
This routine is very easy/fast to learn and does not require any gaffs at all.
Can be done totally impromptu.
Lighing up flash Sharpie sold separately at Penguin Magic, but not necessary to do the routine.
