Linking Rope Loops by Mr. Magic - Trick

Magician shows three different colored ropes (red, blue and green) and calls two spectators onto the stage. He gives each a color rope of his choice, and the magician holds onto the remaining rope. Magician asks the spectators to tie their ropes in a circle with a genuine knot and he, too, does the same with his piece of rope. Without switching the ropes or tampering with the knots, he proceeds to link the solid rings of rope! Finally, the spectators are asked untie the ropes, and to verify that the knots were indeed genuine.

Looks fabulous, and amazes the spectators and your entire audience!
