Two spectators are asked to examine a 15 foot length of rope. They then hold the rope, one spectator at each end. A spot is selected somewhere near the center of the rope. The slack is taken up, and the rope is openly cut using a large knife.
The cut ends are tied together in a solid knot.
The knot is then slid along the length of the rope!
Sliding the knot near one end of the rope, you untie the knot, leaving the spectators holding two uneven lengths of rope! A killer effect!
Knot Unexpected is really quite easy to do. The special props do just about all of the work for you! Comes complete with Jim Steinmeyer's routine and special knife.
As performed by Doug Henning on TV!
