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.

Two Indians were standing next to a river taking a piss.
The first Indian said, “Water’s cold”.
The other one said, “Deep too”....
As someone said about a related study long ago, no subject is too great or too piddling for scientific research.
I always tell my urologist he needs to have a little sign over his door
“Pee Like a Champion Today”
did they really spend money on this?
taxdollars?
I think the best way is to use enfilade fire. The Germans did this in WWI. You shoot high and let it drop in on the target. I usually stand about eight or ten feet back and enfilade it. Worked fine until that guy in the Atlanta airport wasn’t paying attention and walked through my field of fire.
I dont think the problem is splash, it is drips that land on the floor and bowl from standing too far away. At work it is not unusual to have yellow drops on the floor under the urinal. In order not to step in them people stand farther away and that just makes the problem worse. Just stand closer to the bowl/urinal and the problem is solved.
For some of us it is not necessary to stand close.
Pi$$ on it!
Cornell did a major study on bathrooms in the 1960s and nothing changed, although they called for a number of changes, lowering the toilet, installing urinals in all bathrooms were two of the major changes.
PC dominates American bathrooms, not only in the home, but in commercial baths, for instance those urinals that are down below your knees and the toilet that is so high, that is a stupid idea, but the government makes them do it.
Ah....
“For some of us it is not necessary to stand close.”
Which makes our wives very happy.
Green Tea and Saw Palmetto— trust me on this!
Remember the expression “p*** like a racehorse?
You don’t lower it.
Downwind is my advice. Don’t ask how I know.
That used to be called the “Motorman’s Friend”. Back in the day when cities had streetcars and work rules didn’t provide for breaks, the motorman on a streetcar was stuck in his seat for his entire shift.
The ‘motorman’s friend’ was hidden in a pants leg and all was well.
This a time they should reach across the aisle.
