You borrow a finger ring from a spectator and place it in your closed fist. When your hand is opened, their ring has vanished!
You explain that they shouldn't worry...last time this happened, you found the ring out in your car. You reach around to your back pocket and bring out your car keys. Clipped to your key case, in the middle of all your keys, is their ring!
Ring Flight comes with a fine quality leather zippered key case and instructions.
