The "wizz-kids"at Brigham Young University have been hard at work trying to find the best method to spray the porcelain. A team of four scientist have developed methods on how to avoid urinating on the wall, floor and pants all at the same time. I guess I have been doing it wrong my whole life, but I blame my mother because she taught me. Now I wonder what else I'm doing wrong. 

Here's how the fellas can avoid wetting themselves: 

In analyzing their results, the researchers found that sitting on a toilet, as most men well know, results in the least amount of splash-back (the contact point is much closer). They also discovered something likely few men have considered—that urine follows what is known as the Plateau-Rayleigh instability—where a pee stream breaks up into drops before striking something else. That's the worst thing that can happen, the team reports, because each drop creates splash-back. To avoid that, men should stand as close to the urinal as possible they advise. Also helpful is directing the stream to hit the back of the urinal at a downward angle. That creates less splash-back and the drops that do bounce, head downwards into the urinal drain. Conversely, to prevent messing one's trousers (or angering neighbors) they suggest men not spray directly into the urinal or into the pool that forms at the bottom of the urinal, both cause a lot of splash-back.
