For those who lack optimal anti-splash technique, another of Truscott's graduate students, Randy Hurd, presented an optimal design for a splash-free urinal insert at the 2015 APS fluid dynamics ...

You're taking the p***! Scientists develop the ultimate URINAL with a narrow opening that prevents ANY splash-back. The problem of splash-back at urinals has persisted since their invention ...

Urinals, first invented nearly 200 years ago, have a notorious flaw - splashback. Now, experts have come up with a design that solves this problem using the basic principles of physics.

“This urinal design project is the best teaching tool I can think of, as it is a daily-life problem that covers numerous topics—including fluid mechanics, sustainability, differential ...

The Main Drain isn't shy about its bathroom habits. The detachable and adjustable urinal aims to make toilet time more convenient for guys. Freelance writer Amanda C. Kooser covers gadgets and ...

Weber State associate professor Dr. Randy Hurd and his collaborator Zhao Pan at the University of Waterloo in Canada have created two new urinal designs — the Cornucopia and the Nautilus — that reduce ...

Good news for khaki-clad men plagued by speckled staining of their trousers from urine splash back: physicists may have found the optimal splash-suppressing design for a urinal insert, thereby ...

If you've unclogged a toilet before, you likely know that sometimes the water can splash out at you. There's a simple trick to avoiding such a tragedy.

That splash is due to a fluid dynamics term called the Rayleigh Instability. Basically your stream loses power about 6 inches from the urethra, scattering your spray into messy droplets. With a ...
