You don't always walk away from a TED Talk feeling like you've learned something useful, but this time you will. Joe Smith presents a simple but incredibly useful technique that guarantees you can dry your hands using just a single square of paper towel.
The technique uses a pretty basic shake and fold approach, which takes advantage of something called "interstitial suspension" with the paper towel. We're assuming that means it makes it more absorbent. And besides letting you leave a public washroom without having to wipe your hands on your pants, the technique will of course also drastically reduce the amount of paper that's wasted in bathrooms where hot air hand dryers aren't installed.
