How to help men stop the scene of

Tragedy shooting urine on pants, on shoes, on hands . will be terminated immediately.

Women 's wings kept telling them a lot of injustice, but in fact, the men' s wings were very difficult to deal with. Even the "small house" story must be careful, miscellaneous is splashing like this.

The story of "splashing" of his son every time he urinates.

In fact, this story of splashing when urinating is inevitable. The reason is that "water flowing at the source" does not follow a fixed stream, but is divided into many drops . That is, like you throw a water ball away, the water droplets that collide with the urinal surface immediately burst and splattered everywhere.

This shot is random, so depending on luck, the master's tragedy will have different levels. Lightly shot around, heavy, go into the hands, into pants, into shoes, generally suffering.

And don't think this is funny! The splashing of urine may be the source of a lot of dangerous bacteria and diseases. This is why you should not go to the restrooms of hospitals, even if they have regular disinfection.

How to solve this?

Fortunately, scientists at Oxford University (UK) have successfully developed a solution to prevent this spattering situation. It is expected that it will be applied not only in the toilet, but also in the kitchen sink.

This method is extremely simple. Experts said that just by applying a soft layer of material to the urinal surface, such as rubber or gel material, the amount of water shot up would be greatly reduced.

Specifically, the team used ethanol (alcohol) to simulate urine flow, then poured them onto a surface with silicone - because this is a popular and highly customizable material. This process is recorded by a high-speed camera (about 100,000 frames / s).

Test drops of water on hard and soft surfaces.

The results are amazing, this shot is completely eliminated!

According to Alfonso Castrejón-Pita, professor at the Royal Society of Oxford: "This experiment, when combined with research models and simulations from computers, we realize that the contact surface only deforms properly. 30 microseconds, that is, the shooting of the water is completely eliminated. "

"What's even more surprising is that we have to shoot 70% more energy than usual to allow water to reflect on such soft surfaces. That is, we need to urinate at twice the height. compared to normal new spattering " - he said.

Professor thinks this solution will have applications beyond the toilet or kitchen. Even laboratories should consider using them.

The spread of liquid drops when falling is extremely easy.

According to him: "The spread of liquid droplets when falling is extremely easy: a drop of liquid such as ethanol or methanol if dropped from 20cm height will form droplets of sufficient size to spread through the air. "If we have to work with dangerous chemicals in liquid form, it will be necessary to make sure that dropping them doesn't make us suffer."

"Even in surgery, it can be applied, body fluids will not splatter during surgery," he added.

Going back to the toilet bowl story, how to do it specifically? Simply put, add a rubber band like this to finish. When urinating, remember to be in the right position.

Put an extra rubber ring here is okay.

Or if not, find a way to stand as close to the urinal as possible. If the urine flow does not break into small droplets, the ability to shoot is also greatly reduced.
