ADVERTISEMENTUS physicists studying urine “splashback” say men should consider sitting down to pass water.
Experts from Brigham Young University’s Splash Lab simulated a toilet scene by filming a jet of liquid hitting a body of water.
The team, who had their research published in Physics of Fluids, said: “This stream of water is a simulated urine stream entering a body of water similar to a toilet.
“The amount of splash is considerable and should make one reconsider standing up to urinate.
“The repeated impact of the droplets opens up a large and interesting cavity with multiple ridges. Each droplet forms a small cavity wherein the next droplet can pass through and form a cavity an additional cavity creating a chain of small cavity structures. Splash is formed both from the initial impact as well as the collapse of this large cavity. The process repeats itself over and over creating a real mess.”
