To be honest, I'm not sure if this key will replace my folding coin from Tango Magic, but as a novel variation, this cool gimmick is hard to beat. You get the folding key and a matching regular key. Take both to a locksmith and have the teeth cut to make it look like any other key. The gimmicked key looks like a normal house key (it is silver with a round top) and uses a sturdy clear plastic elastic thread rather than rubber bands, so it should last a very long time. I have found replacement thread at my local craft store, although I have yet to replace it. Combine the key with other effects using keys (key bending, pendulum, Key Master by Craig Petty) and you will have a very solid set of different effects using a common object. Audiences are interested in keys (because they are personal and we all have them) more than Morgan silver dollars and chop cups. Just keepin' it real...
