Why is it necessary to lower the toilet lid before flushing

Modern scientists in between studies the mysteries of the universe and attempts splitting of elementary particles sometimes have time to do something really useful. For example, to open a phenomenon which they called "trail toilet".

The first toilet was invented around 1596 by Sir John Harington (John Harington) for Queen Elizabeth I. The timing of the toilet lids do not know exactly, but we can assume that they were created by a after the first and toilets were designed to prevent the spread of bad odors by royal apartments.

Despite a long history of disputes about the correct use of caps do not cease to this day. You need to close them or not? If you want to, when?

The answer to this question give microbiologists. According to their research, each time when flushing water over the toilet rises spray column height up to 2 meters, consisting of water, air and particles of our bowel movements. It was he who called the toilet train.

The particles and bacteria from feces of this cloud spread to a distance of 4 meters. As published in the Journal of Applied Microbiology in 1975

Of course, the number of particles and bacteria from entering the toilet on the toothbrush as a result of a plum, is negligible. But the problem is that they can accumulate and multiply there, the more that the environment is favorable to this. And this is no joke.

So what to do? Scientists are advised to observe the following rules:

• Always lower the toilet lid before pressing the flush button.
• Keep toothbrushes and personal hygiene items away from the toilet. It is advisable in closed boxes.
• If you use a public toilet, try to get out of the drain water.

But most important, scientists say, not to neglect the elementary rules of hygiene. For example, each time to wash your hands after using the toilet. Well, what we know so well, right?
