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.

Pee barefooted - get smart fast.
The ADA started making places put in those urinal for midgets. If you go into a bathroom with the taller and the smaller urinals, look on the floor and you will see that the floor under the shorter urinal is always wet. I don’t know why they did this but like all Govt. ideas it doesn’t matter if it works or not, once they do it , they won’t change.
Any boy who hasn’t got the angular requirements of urination figured out by the age of 8 is a dim bulb.
My hands were cold this morning !!
Yikes !
Put your foot in the bowl and pee down your leg. No splash.
Position tree in front of body slightly to the left of the stream.
This really pisses me off.
And to raise the lid, I manufacture a handle - the Johnie-Lift, for the germaphobes.
Excellent training / teaching idea! LOL
Doesn’t matter how you jiggle, doesn’t matter how you dance, the last two drops gonna land in your pants.
If you shake it more than two times you are playing with yourself.
Put that bastard that’s in the white hut in range and I’ll show you spashback!
It can be done with the side of your shoe.
There could be an instructional sign posted, informing women who do not understand how to operate the toilet seat.
Piss on him!
My extensive studies indicate that it’s more efficient to sit at home and stand everywhere else.
I used to listen to a Master Gardener named Jerry Baker on the radio....he was a huge proponent of peeing around your trees to add some nutrients.
Anybody who has peeing in urinals or toilets for more than a year has already figured this all out....
Considering the college is in a county which voted 7-1 against ObaMao, I'd say the odds of any federal funds being used was slim to none. It also happens to be the most conservative city in the U.S.A. There was an interesting compare and contrast post with Detroit, the most liberal city in the U.S.A., which pointed out a huge disparity in livability despite remarkable similarities in income.
So when does my local Community College list a pee training class in the syllabus?
