A rope is cut at the middle and the two pieces are tied together with a knot. One end of the rope is tied to the microphone stand or a chair and the other end is held by a spectator.
The magician moves the knot from the middle of the rope, down towards the end of the rope and unties the knot showing that the cut moved with the knot. He then ties the ends together again and moves the knot all the way to the opposite end where the spectator unties the knot himself showing two separate ropes.

The cut is shown at three different locations on the rope using three different methods! The ropes are shown to have different lengths every time! Easy to learn!
