Toilet water splash gif5/1/2023 the Splash Lab didn't use "in the field" testing. As you can probably imagine, for a variety of reasons - hygiene, ethics, controlling for environmental factors, repeatability. Hybrophobic surfaces, such as on your car's windshield or smartphone screen, would reduce splashback a lot. Porcelain, for example, is hydrophilic, causing urine to form puddles, which then cause splashback when hit by more urine. The physicists also note that various materials, baffles, and other obstacles (urinal cakes) can all make a big difference. As you can see in the (strangely mystifying) video below, peeing into a body of water creates a cavity that then collapses in on itself, creating massive splashback. Other ways of reducing splashback include not peeing directly into the water, and laying down an shock-absorbing layer of toilet paper before you begin. Sitting down usually implies a narrower angle of attack, too. The other easy way of saving your marriage is by simply sitting down: Your pee travels five times farther when you're standing up, picking up a lot of velocity on the way, creating far more splashback. Pee splashback is caused by two main factors: height from the toilet/urinal bowl, and the "angle of attack." By far the best way to reduce splashback is to alter the angle of your pee stream so that it hits the wall of the toilet/urinal at a gradual angle the closer to 90 degrees, the worse the splashback will be. Their urinal dynamics research provided some interesting findings - though they're not entirely unexpected if you're an enlightened male. They're so confident that they're going to present their findings to the American Physical Society. Truscott and Hurd have spent the last few months analyzing the male urine stream, and with a bit of applied fluid dynamics - and a healthy dollop of high-speed camera footage (embedded below) - they think they've finally worked out how to pee without creating splashback. I am of course talking about the nasty habit of urine splashing out of a urinal or toilet and onto the floor - or worse, the urinator himself. To you and I, it's called splashback - for physicists Tadd Truscott and Randy Hurd of the Brigham Young University Splash Lab, though, it's called urinal dynamics.
