Paper Towels

I occured to me today how much paper towels are wasted in public restooms. I saw a guy give the dispenser 7 solid pulls before he dried his hand with only the middle section. Then I wondered how many pulls you needed to actually dry your hands. In my test I got them fairly dry with three pulls (about 8 inches of paper). When I finished the paper was nearly completely wet but my hands where dry. If we could control ourselves we wouldn't need to have the air hand driers.
