Show three lengths of rope, each of a different length. One is long, the second is of medium length, and the third is a short piece.
Gathering the ropes together, you give them a deft tug. As if made of rubber, the ropes magically stretch and shrink. They are now all the same length!
The ropes are counted, each one seen to be the same length as the others. Then, just as magically, they revert to their original state - three unequal ropes! Everything can now be examined.
The Professors' Nightmare is easy to learn from these illustrated step-by-step instructions (in booklet form). All of the necessary details have been described and illustrated. Three pieces of special, professional-grade rope have also been included so you can get started right away!
Bonus tricks included!
