Show a small cloth bag with a white nylon front to be empty.

An invisible coin is flipped in the air and caught in the bag - see a coin (quarter) actually appear in the bag! 

This is done a second time and the coin completely vanishes. 

Also, change two quarters to a half dollar. 

Lots of possibilities!

1 Coin becomes 2 or 3 or more coins!

Sale includes gimmicked bag and instructions.
