The physics of urine "splashback"
US physicists have studied the fluid dynamics of urine "splashback" to help men and women improve their accuracy.
The team from Brigham Young University's Splash Lab filmed a jet of liquid entering a body of water similar to a toilet.
"The amount of splash is considerable, as the repeated impact of the urine droplets opens up a large and interesting cavity," the researchers said.
"Splash is formed both from the initial impact and the collapse of this cavity. The process repeats itself over and over, creating a real mess."
