Urinal Dynamics: How To Avoid Splash
BYU's Splash Lab (yep, a real department at the University) recently conducted a series of experiments in urinal dynamics--the study of the physics of bathroom usage. Using high-speed video and simulations of male urination in both toilets and urinals, the researchers prescribe the best angle of attack to reduce hazardous splash. Their recommendation: aim for a vertical surface and at a decreased angle to reduce bounceback, and stand close enough to the urinal to prevent the stream from becoming individual droplets before they hit the surface. Maybe it's time to move those urinal fly decals.
