The Magician hands a set of three ropes to a spectator and keeps
a set for himself. The Ropes have colored tips on the ends to
distinguish between them. The spectator ties the matching ends
of each rope together to make three loops.
when the magician does it he gets one large loop.
The magician's ropes are prepared differently from those of the
spectator. Notice that the ends of each rope don't match, so when
the magician ties his ropes together,they will form one large loop.
Be careful when you tie the ends that you don't tangle the ropes
and end up with a knot in the loop.
