The magician is going to show the audience how an ordinary piece of rope can be cut in half by the special cutting machine and then instantly restored. This is how you do it:
First of all, show the ordinary piece of rope to the audience. Let them feel it and give it a pull if you like.
Put the rope through the cutting machine and then push the machine apart. The rope appears to be cut in half and through the apertures of each block, the spectator will be able to clearly see the cut ends.
now push the two blocks of the cutting machine back together again and the rope will once again be in one piece. Slowly pull the rope back out from the cutting machine to demonstrate this to the audience and wait for the applause!
