Ring & Spring Puzzle

A pocket-sized puzzle that doubles as a magic trick. The object is simple: remove the brass ring from the silver spring. Once you succeed, can you lock it back in place again? With a bit of practice, you can learn to solve this puzzle in plain sight without giving away the necessary technique. That makes the Ring and Spring a great demonstration puzzle. Mystify your friends by solving it easily, over and over again while they fail to remove the ring no matter how hard they try. You can even offer a false solution by executing the secret move with a bit of misdirection. "It's voice controlled." "It only works when you close your eyes." Etc. Harmless fun though, a bit evil.
