If you go to the men’s washrooms at the Schiphol airport in Amsterdam, you may notice there’s a fly in the urinals. So what do you think most men do? That’s right, they aim at the fly when they urinate. They don’t even think about it, and they don’t need to read a user’s manual; it’s just an instinctive reaction. The interesting feature of these urinals is that they’re deliberately designed to take advantage of this inherent human male tendency. The fly isn’t really a fly. It’s a drawing of a fly, permanently etched onto the porcelain. And the etching isn’t placed in just any old location on the urinal. On the contrary, it’s been strategically etched into the “sweet spot” of the urinal, the point of curvature that minimizes splash back.
Someone give that designer a medal!
