Amazing piece of quality pocket magic- and perfect for the strolling magician!
Simply borrow a ring from your spectator and place it on a solid brass bolt. Let your spectator screw a nut on each end. The ring is now securely locked on the bolt- it can't slide off past those nuts. Then you put a padlock through the bolt- and lock it! There is NO WAY the nuts or the ring can be removed from the bolt now!
Of course, YOU can INSTANTLY get the ring off the bolt! You just place a silk handkerchief over the bolt and have your spectator cup his hands under it. At your command, the ring drops right into the spectator's hands! Very startling!
Best of all, though it would take your spectator some time to unscrew the nuts from the bolt to start the trick again- it instantly resets for you because you know the secret!
Machined from solid brass for years of trouble-free use.
