Pavel's Knot Factory

One, two, three, four, and even five knots appear in a piece of rope, all at the same time! The magician starts by holding the rope between his hands. He gives the rope a twist and the knots tie themselves snuggly and equally spaced in the rope. The procedure looks almost the same, but each time the magician ends up with a different number of knots. Complete routine, five different colored ropes with special knots.
