For those men who often wore khaki slacks, trousers are urinal spilled urine to wet your pants is a very annoying thing. And now, the good news is that scientists may have found the best splash-proof design, urine into the urinal is like entering a "black hole", never spilled. GUCCI iPhone
Starting from the 19th century, people wearing khaki trousers have been beset by urine splashing about. Therefore, the Splash from the Utah State University Lab Director Tadd Truscott Randy Hurd and his graduate students began to undertake relevant studies, and earlier this week the United States physics fluid dynamics Conference published their findings.

As early as 2013, Splash Lab (at that time also belongs to the Brigham Young University) gave us the boys how to avoid urine splashing khaki pants are the best skills. Sitting on the toilet is the best approach, especially for those of you who is reading a book or playing a game.
If you have selected a classical stance, scientists propose to you as much as possible from the urinals near some and let the urine flow down the urinal behind, this produces less splash. However, not everyone knows this, of course, some people probably couldn't care less about your urine splashing everywhere are (if you think so, then I can only say that you win).
Therefore, Tadd Truscott and Randy Hurd turned a urinal mats research. They hope to find an ideal urinal pad design, let the pee on the wrong side or simply do not care this can effectively prevent the urine splashing your pants.
Randy Hurd said he studied many different design after the discovery, the urinal pad can be divided into three categories. First class uses the absorption of very strong fabric of urine splashing to a minimum. However, these fabrics do not absorb liquids quickly and easily saturated, saturated after the urinal mats will make the problem worse.
Type II uses a honeycomb structure, there are many small bumps and holes on the mat, urine after you enter will not be able to splash out. This cushion works well, but their efficiency is not high, easily lead to stagnant water (or urine deposition). Third class uses rows of small spines, they look to be the best, but piercing high enough so that they do not prevent urine splashes.
Tadd Truscott and Randy Hurd began thinking about how to improve the barbed urinal pad they found inspiration from a superabsorbent Moss this moss grows in very dry environments, water absorption and water properties are very good. Researchers said that they had just completed a study on the mosses of special study on micro-structures, they found that this structure can drop into MOSS, and also to prevent splash of droplets by deformation.
The next problem is that they have to find a substitute to the Lichen material. Tadd Truscott and Randy Hurd said: "we have found a structure made up of carbon nanotubes, light and then never come out. In our view, if it's useful to light, then drops or urine may also be effective. "
In other words, it is a black hole simulation, urinal mats and researchers used a similar structure, in order to find the best splash-proof design, they use simulated urine splashing of the water droplets, and tried to identify the most suitable length of the spines and interval.
Finally, compared to reduce splashing urine, and they are more physical problems is the study of droplet impact. Randy Hurd said: "we found that urine splashes and links between the urinals are very interesting and believe that the scientific community will be interested in interactions between them. "
