The physicists also note that various materials, baffles, and other obstacles (urinal cakes) can all make a big difference. 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. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws.

Use the sink instead. 1996-2022 Ziff Davis, LLC. 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.

First, a falling stream of liquid accelerates due to gravity, and therefore, it tapers as it falls to maintain volumetric flux, Novario says.

If you hit the wall of the urinal at the right angle, then there will be no spashback. In addition, your urine picks up a lot of velocity the farther you stand from the urinal, resulting in more splash back. Because of the unstable pressure difference left by this cavity, layers of the reservoir liquid rush in to fill this gap and collide with each other at high speeds, causing the colliding liquid to be ejected upwards, and essentially sending pee flying everywhere. They then filled the apparatus with colored water, set up a high-speed camera, and systematically synthetically urinated on a variety of different targets.

Unfortunately, due to the chemical makeup of urine and the physical, ahem, limitations of the apparatus that produces it, a stream of urine breaks up about 6 to 7 inches after exiting the urethra. The downward force of the flush water helps reduce spashback, or something. The thinking is, this will at least block some of the splash-back from getting on walls and floors. Although there are some urinals that are terribly designed. This increases the surface area and the energy associated with surface tension. From there, the urine falls into a lower energy state by collapsing into droplets with the same volume but lower surface area..

The key is to find a good compromise between angle of the stream and splash from vertical surfaces, Novario says, which can best be found on the left and right walls of the toilet.
