Challenge Knot Tie
Challenge your friends to tie a knot in a piece of rope without letting go of the ends. None of them will be able to do it, but you will!
 
REQUIREMENTS: A piece of rope 3 or 4 feet long.
 
This is an easy one, but it will baffle people who don't know how to do it. Hold the rope from the ednds and give your friends a chance to try to tie a knot in the rope without at any time letting go of either end.
 
When they give up, take back the rope and lay it down on a table. Now for the secret move: Cross your arms before you pick up the rope!.
 
Pick it up one end at a time to make it easier to grasp. When you uncross your arms, a knot will appear in the middle of the rope, without you at any time releasing either
end!
