Ultra gimmick

This is a wonderful gimmick that will allow you to perform incredible effects. A coin on the palm of your hand amazingly vanishes by simply passing your other hand over it.   A coin changes into a completely different one.   A ring stays magically suspended to another one and can even be spun around in this position.   • And many more… • The changes and disappearances happen in an instant and the extraordinary thing is that the hands each time are totally "clean".
