In this short talk, Oregonian paper towel expert* Joe Smith explains how to dry your hands using a single paper towel. He gives a series of demos, boiling down to two crucial steps: shake and fold. Now, I'm no paper towel scientist, but this sounds like a great way to save a lot of paper -- and I admit, I'm guilty of routinely grabbing two or three of those "tri-fold" towels, wastrel that I am.
Now let's save some trees, one paper towel at a time. Who's with me?
* = Smith is also former chair of the Oregon Democratic Party, though his technique works for anyone who gets his or her hands dirty.
