Disk Escape by Kreis Magic

There are a blue and red face poker chip, and a metal disk. Before the performance, both faces of them are shown to the audience. A rope is threaded through holes in the center of them. A spectator holds both ends of the rope. Then, the magician grasps the chip and disk. It is impossible to remove the poker chip or the disk off the rope, but he does. The disk is pulled off from the rope. 

All the items are examinable immediately after the performance.

Comes complete with 2 disks, rope and an illustrated instruction sheet that includes web links for additional performance and explanation video clips.
