For a moment today, I thought that I had discovered a breakthrough in hand drying technique. As I washed my hands this morning in the bathroom down the hall from my classroom, it occurred to me: there are two hand-dryers, and I have two hands. Why not turn both of them on at the same time? That way, each hand would have the benefit of getting the full force of its own hand-dryer.
I tried it immediately, and soon noticed that what this technique does not have is the drying effect given by step #2, "Rub hands gently." As a result, the machines turned off with both of my hands slightly less dry than they would have been had I used a single dryer. A major disappointment.
I guess that's why step #1 isn't "Push button on two dryers if available."
