Linking Ropes by Ronjo - Trick

Effect:You show three ordinary pieces of rope, each about two feet long. A spectator ties the ends of each rope together, forming three separate rope rings. You link the rings together without untying them.
Then the rings are unlinked, again without touching the knots. Finally, the spectator unties each knot. A very visually exciting routine built on one of the best effects in magic!
