Ultracinese is a PK effect that offers one of the most astonishing experiences in magic. Picture threading a nut and bolt together, and then, at your command, the nut mysteriously unscrews itself, seemingly guided by unseen forces. You can even reverse the action and wind the nut back onto the bolt. The best part? No threads, magnets, reels, rubber bands, or hidden devices – nothing attached to the nut or bolt, and no switching involved. The package includes the handcrafted gimmick powered by a simple AA battery (not included), comprehensive written instructions, and a bonus DVD for in-depth handling guidance.
