Professor's Nightmare / Equal Unequal Ropes

Performer shows three separate pieces of rope each of a different size. 
There is a very short piece, a medium size piece, and a long piece. The performer folds the three pieces and when the ropes are opened out again all three pieces are seen to be of  the same size. A perfect illusion. If required the ropes can again be restored to their original different sizes and tossed out for examination.  
We supply you the three colored deluxe cotton ropes of the correct different sizes for this effect, and easy to follow illustrated instructions in full color..
