Using more than one paper towel to dry your hand is irresponsible. The default size of a paper towel that comes out of those dispensers are more than enough to take more than one. Joe Smith, demonstrates the perfect paper towel technique, by shaking and folding.

Why do this you ask? There are 13 billion ponds of paper towels used only in America alone, what more of the rest of the world? Check out the video below:
