Suppose you have two pieces of tape, each 12 inches long and 1/2" wide.  You could tape them to a wall at right angles to obtain one right-angle crossing point.  If you had four pieces of tape, you could make a pound-sign (#), and get four right-angle crossing points. 

Is there a way to start with three pieces of tape, and stick the tape to a surface to get six right angle crossing points, without folding or tearing the tape?
