For guys, there's nothing like going in to take a pee, only to have the pee splashback against your leg. Anthony looks at the science of the pee splashback and what you can do to keep you clean and dry.
BYU Splash Lab
"The Splash Lab seeks to unravel the physical mechanisms of fluid behaviors, through a novel 3D volumetric measurement method known as Synthetic Aperture Imaging and embedded instrumentation (e.g., accelerometers, etc). We experimentally analyze fluid systems such as fluid-structure interactions, multi-phase flows, and free surface phenomena."
"The Plateau-Rayleigh instability, often just called the Rayleigh instability, explains why and how a falling stream of fluid breaks up into smaller packets with the same volume but less surface area. It is related to the Rayleigh-Taylor instability."
Urinal Dynamics: a tactical summary
"We illustrate the importance of good technique when using a urinal and offer some advice. Through high-speed video footage of a simulated male urine stream we show that reduced splash can be achieved by aiming at a vertical surface, moving closer to the urinal and by decreasing the impact angle."
"In response to harsh and repeated criticisms from our mothers and several failed relationships with women, we present the splash dynamics of a simulated human male urine stream impacting rigid and free surfaces."
