The magician displays a ring on a spring about 3" long which is closed in at the ends. A spectator is invited to try and get the ring off the spring, but can not do so. The magician simply blows on the spring and shakes it, and the ring falls off the spring.  

This is great for a comedy bit. Hand it to one person but they can't do it. Hand it to another spectator (the birthday child or company CEO) and they succeed!

3" long with .5" diameter ring.

Pack of 12.
