Four Ended Rope

This is one of the clever-est Rope tricks every devised! You begin with an ordinary looking piece of rope with – three ends(?) Where is the third end? Suddenly a third end appears and then a fourth! You now have two pieces of rope. But wait – suddenly magician changes the two pieces back into one rope. A knot is tied in the center and rope is coiled and thrown into the air – when it comes down it has three knots in it! Completely self – contained and a real fooler!
