If you haven't seen the urinals that they use in the Amsterdam airport, here is a picture. There is a black fly etched into the urinal. You might be asking yourself: why? Why would they etch a fly onto a urinal? Well, the reason is simple: spillage at the airport has dropped by 80% because of the fly. Apparently, if you give a man something fo focus on, they stay on target. Richard H. Thaler and Cass R. Sunstein's talk about this in their book Nudge. They state "tiny changes in environment can influence behavior" and they call this "choice architecture." I think its great that men need to have something to focus on when using the bathroom to avoid spilling. There are now even companies that have been created following the Amsterdam model. The Urinal Fly company gives you stickers that are guaranteed to stay on the toilet.
