Fellas, if you think your 'good aim' when peeing means you aren't getting wee all over the place, then I have some news for you.
Because a series of grim UV tests has shown that tiny droplets of urine can splash as far as 36 inches, almost an entire metre. Lovely, eh?
If that's not quite gross enough for you, one in four people quizzed by the researchers said they kept their toothbrush within 36 inches of their toilet, meaning there's a good chance they're inadvertently brushing their teeth with pee.
Tests carried out by QS Supplies, found that 69 percent of men stand when they pee, and 31 percent of those men aim for the back of the toilet bowl, thinking this will cause the least amount of 'splashback'.
Unfortunately for those guys (and anyone who has to share a toilet with them) it actually creates more splashback than any other aiming technique the testers tried.
If you're interested, the study goes on to explain that when peeing from a standing position, thousands of droplets of urine are created and can fly into the air and land in the surrounding area.
Mostly, these can't be seen, which is why the guys from QS Supplies whipped out a mechanical urethra, florescent liquid (to recreate wee) and the UV light. Sounds like an... erm, interesting week in work for those guys.
Then they set about re-creating every element of standing up weeing including 'volume, flow rate and curve, trajectory and stream shape'.
They found fellas aiming for the rear wall of the toilet bowl created the most droplets and the widest spread.
Those who aim directly into the water, which is 29 percent of blokes, by the way, produce a smaller number of large drops and cut 'excessive splashing' of tiny drops. Spread was also reduced.
So, which is your best bet if you don't want wee all over your lovely clean bathroom? Well, the researchers claim that for the biggest reduction in splashback, men should aim at the 'nearside of the bowl, just in front of the water'.
However, they also pointed out that whichever technique you use, standing to pee produces splashes.
They wrote: "In every simulation, no matter which surface we aimed at, the UV light revealed some number of droplets flying onto the toilet rim, the underside of the toilet seat and lid, the floor or all of the above."
