Rules: Have your coworkers stand in a circle holding a piece of the rope. Then instruct everyone to put on their blindfold and set the rope on the floor. Have everyone take walk a short distance away from the circle. Next, ask everyone to come back and try to form a square with the rope without removing their blindfolds. Set a time limit to make it more competitive. To make it even more difficult, instruct some team members to stay silent.
Decent length(s) of rope for numbers
