Professors Nightmare - Colored Rope
Three ropes of unequal length are shown. The ropes are then
'stretched' to equal lengths. The ropes are counted one at a time.
Then just as quickly as they became equal length, they revert back
to their original unequal states. Don't let the low price fool
you, this one is fantastic.
