Revoke by Gianni Vox
Physically move reality.
You're at a party with your friends. It happens. They ask you to show them a trick and they want you to use their things...
In comes Revoke by Gianni Vox. Using a borrowed Sharpie (Permanent marker... none of that dry erase garbage) you have a spectator sign their initials on THEIR OWN COIN. You draw an 'X' on the other side of the borrowed coin. You show your hands completely empty, then wave your hand over the 'X'...
The 'X' vanishes, you move your pointing finger along your arm, up your other hand and on to the back of your hand! It's permanent. It's not wiping off.
THAT is Revoke!
Revoke has been designed with the impromptu street magician in mind. You can walk into a party with next to nothing and perform this miracle with all borrowed objects.
-This is the effect you've been waiting for. It's small, will fit in ANY pocket (even little tiny ones). You are always ready to perform this miracle.
-Everything is examinable at the end, because everything is borrowed. Never get caught with some weird gimmick you can't explain.
-You leave your spectator with the impossible coin, missing the 'X' of course. They WILL show this to people and talk about it. How could they not?
Warning: You will need to help your friends pick up their jaws off the floor after they see this. This isn't your grandfather's coin trick. This is a coin trick for the new magic generation.
