Moving a Coin Through Glass Trick

Place a penny or a dime on a tablecloth, towel or napkin and cover it over with a glass in such a way that the glass will rest upon two 25 or 50 cent pieces as shown in the sketch.
The coin is made to come forth without touching it or sliding a stick under the edge of the glass. It is only necessary to claw the cloth near the glass with the nail of the forefinger.

Removing the Coin

The cloth will produce a movement that will slide the coin to the edge and from under the glass.
