With carbon nanotubes, men can have fun in the toilet

I believe many people have had this experience: when peeing, you must be very careful and aim at the lower middle part of the urinal to prevent urine from splashing and staining your pants or shoes. In fact, this is not just a problem for one person. Scientists have also been troubled by solving the problem of urine splashing.

Back in 2013, Splash Lab brought us the best tips for guys to avoid getting their khaki pants wet with urine. Sitting on the toilet is the best way, especially for those who are reading or playing games. If you choose the classic standing position, scientists recommend that you stay as close to the urinal as possible and let the urine flow down the back of the urinal, which will produce less splashing. However, when a person is particularly anxious or does not pay attention to these details, the consequences, I think you know.

The good news is that scientists at Utah State University in the United States recently successfully created a "urine black hole" using carbon nanotubes, which can completely lock urine and prevent splashing.

When urine leaves the body, it inevitably evolves into smaller, more unpredictable droplets that fall into the urinal. When these droplets hit the urinal surface at different angles and speeds, splashing may occur.

At present, the anti-splash equipment on the market is mainly urinal pads. They are mainly divided into three categories:

The first category focuses on minimizing urine splashes by using highly absorbent fabrics. However, these fabrics do not absorb liquid quickly and become saturated easily, which can make the problem worse with urinal pads.

The second type uses a honeycomb structure with many small protrusions and holes on the mat, which prevent urine from splashing out. These mats work well, but they are not very efficient and can easily cause water (or urine) to accumulate.

The third type uses rows of small spines, which seem to be the most effective, but the spines are not high enough to prevent urine from splashing.

Researchers at Utah State University borrowed from the highly absorbent moss plants in nature and used a material called Vantablack, which is made of carbon nanotubes and can absorb 99.96% of the light that shines on it. Traditional black pigments and fibers can only absorb 95% to 98% of light, making it the blackest material ever created by humans. However, in toilet applications, after modification, it will no longer trap light, but urine.

My fellow men, you no longer have to be so careful when peeing in the future, isn't it time to celebrate?

However, isn’t it a waste of resources to just use it in toilets? It is said that this material is very expensive (the manufacturer has kept the exact price confidential), and its application has always been very high-end:

1. Astronomy Camera

2. Calibrating a camera that can be used to image the oldest matter in the universe

3. Astronomical telescopes, improve the ability of astronomical telescopes to observe the faintest stars

4. Use infrared scanning system. It can reduce stray light.

5. Military use.

Also, don’t think that spraying this material is easy. It took the researchers four months and more than 400 hours to complete it.
