The performer shows two plastic cups (not supplied).  He pulls an imaginary length of rope from one cup and, after having displayed it as a regular rope, he rolls it around his hand and places the invisible bundler back inside the cup. 

A real length of rope is then pulled out of the second cup.  The rope is knotted in three places and put back in the cup.  A magic pass is made and the invisible rope is taken from the cup and three real knots are seen to be tied in it.  When the real rope is removed, it is free from knots.  Instead of them, three vacant places have appeared in the rope!  Quality made from Pavel from years ago.  Includes illustrated instructions.

Condition unused, like new.
