US physicists have studied the fluid dynamics of urine "splashback" - and found hygiene tips for men and women.
Using high-speed cameras, the team filmed jets of liquid striking toilet walls and studied the resulting spray.
Splashback was low when the jets were used close up with a narrow "angle of attack", said the Brigham Young University team.
They will present their their research at an American Physical Society meeting in Pittsburgh.
"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," reads their conference abstract.
But there is a more serious side to the research.
The work is led by Prof Tadd Truscott and Randy Hurd of the "Splash Lab" at Brigham Young in Provo, Utah, who jokingly refer to themselves as "wizz kids".
"People ask me, are you serious? I tell them yes, this may involve 12-year-old humour, but it's also a real problem," Prof Truscott told BBC News.
"We've all been in disgusting toilets with puddles on the floor - these places are a breeding ground for bacteria."
For example, the detergents used to clean hospital toilets could actually increase the spray of disease-causing bacteria, by reducing the surface tension of water, according to a recent study.
Chaotic spray
One might think the physics of aiming urination had already been summarised by the formula: "get it all in the bowl". But micturation is still a messier business than it needs to be, according to the research.

Just pissin away money.
And, as an added bonus, it keeps unwanted critters away by marking territory.
Had a skunk try to move in under my shed just this fall. Strategic sprinkling sent him moving on.
You correct. Although it seems easier to raise the lid with your shoe than lowering it.
Yep. Urea is pure Nitrogen. However, if you have a female dog the concentration is higher, thus the dead ‘dog spots’ so many have on their lawns, due to Fifi.
I use a 10-18-10 on my fruit trees. They need the added phosphorus (middle #) for good blooming and fruit set.
With some things, too much nitrogen isn’t good; tomatoes, peppers, eggplant - too much Nitrogen and you get big, pretty plants but little fruit. However, greens (lettuces, arugula, chard, collards, mustard, spinach, kale, etc.) LOVE lots of nitrogen, so pee on your salad bed next time you’re out there, LOL!
Gee. Stuff I’ve known since I was four.
Beer is verboten at BYU.
There is another factor that PC academics will not recognize - culture. Having said that, slovenly habits are as American as apple pie just as much as they are third world in origin. In general, there are simply more pigs today than in the past. Doubt it? Start noticing the number of people who leave restrooms (stall or urinal) and walk out without washing their hands. I’m not too squeamish and can do nearly any task no matter how gross, but I believe that simple hygiene should be a routine, basic part or social interaction, but it ain’t anymore. Heck, most major cities have people eliminating right on the sidewalks. We’re taking a plunge back into the middle ages. Protect yourselves.
we built the bomb, we went to the moon, and now, finally, we have figured out how not to piss all over the place as we urinate. hooray for us.
Whiz kids.
“The years passed, mankind became stupider at a frightening rate. Some had high hopes the genetic engineering would correct this trend in evolution, but sadly the greatest minds and resources where focused on conquering hair loss and prolonging erections.” - Idiocracy
yeah, but what about the problem when your effort bifurcates into a stream and droplets?
Most pee is sterile, though nasty to behold.
Poop is far more a disease spread issue and fortunately it’s easier to deal with.
We should try to be neat about the bathroom, but not obsessively so.
Isn't it great to have highly-trained professionals to tell all of us guys what we figured out when we were about four?
It’s cold and deep....but no splash....
I’ll sit down to pee when Hillary does.
“The ADA started making places put in those urinal for midgets.”
I resent that comment. I am not a midget, but due to my age I have a severe handicap. You see I cannot lift anything over 15 pounds and hoisting it up to the conventional placed urinal is painful to both my back and tennis elbows.
Thanks to new rules requiring lower urinals, I now have no pain and no splash.
Now that these physicists have completed this ground breaking research, they can turn to unraveling the ObamaCare website.
Especially if you have a bookshelf next to the appliance...:^)
First saw this in a movie with Burt Reynolds called Semi-Tough. He had to sit thru some 9 hour seminar without even a bathroom break.
The Stadium Pal is a male catheter, a surgical tube, a t-valve and a plastic bag you tie to your leg. I'll leave the exact setup to your imagination.
