PSY-KEY2 ... The Modern Haunted Key! Place PSY-KEY on the table, on your hand, or even on a spectators hand, then listen to the gasps when the key moves and turns over! This examinable key uses no threads or muscle moves. It is easy to perform and comes complete with a PK Prop, which can be used for a variety of other PK effects (See the BAT DVD in our eBay Store). Instructions offer several routines for PSY-KEY2.
