Show a half dollar coin and an empty bottle. Given two or three taps with the coin on the glass and the latter will penetrate the bottle! The currency can be seen through the glass, but how did you penetrate it and how will you get out? Magic!
A classic always fascinating.
Quality Tango Magic.
Pocket-sized and easy to do … to always carry.
An effect that should never miss in the repertoire of a magician.
