What struck Winston Churchill in the Moscow hotel? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? What struck Winston Churchill in the Moscow hotel? Having visited the USSR in August 1942 and staying at the Metropol, the British Prime Minister was amazed that the water flowed without restrictions. Writing about this visit in his book The Second World War, Winston Churchill writes: “I noticed that there were no separate taps for cold and hot water above the sinks, and there were no plugs in the sinks. Hot and cold water, mixed to the desired temperature, flowed through one faucet. Also, you didn’t have to wash your hands in the sink, you could do it under running water from the faucet.” The fact is that in Great Britain and other Western countries, due to the shortage of fresh water at that time, it was customary to use the sink as a filling container: they first took water into it, and then drained it after washing or washing their hands. The following fact testifies to the acuteness of the problem of providing fresh water: during the Second World War, in Buckingham Palace (the residence of the English kings), in order to save water, a line was drawn on all baths at a height of 13 centimeters from the bottom, indicating the maximum permissible level. The problem of the limited resource of fresh water has not lost its sharpness at the present time. So, in modern Germany, only rich people, who are not burdened with environmental consciousness, can afford washing dishes under running water. Author: Kondrashov A.P. Random interesting fact from the Great Encyclopedia: What is nicotine? Recently, when advertising cigarettes, it is increasingly being said that they contain less tar and nicotine. Why are people so interested in this question? Smokers enjoy smoking mainly due to nicotine. A certain amount of smoked has a calming effect on the nervous system. It also "hides" the feeling of fatigue and even stimulates the imagination to a certain extent, which increases the efficiency of some people. One of the main components of tobacco is nicotine. If it is taken in its pure form, then it acts like a poison. But, of course, this is not the case with smoking. Smoking is a kind of "dry distillation" procedure. This means that the dry matter is converted into vapour. The hottest part of a cigarette is its glowing tip. The resulting heat destroys 25% of the nicotine. Further, the cigarette has an average temperature. From here, nicotine-rich gases rise, and 30% of nicotine enters the air. The part closest to the mouth contains cold particles of tobacco, passing through which nicotine settles on them. As a result, only 15% of the total enters the mouth. Filter cigarettes trap it even more. The closer the distance to the burning tip, the more nicotine enters the body. This is why short and thick cigarettes and cigars are stronger than thin and long ones. Re-lit, they burn differently than the first time and retain less nicotine. Of the 15% of nicotine that ends up in the mouth, even less gets into the bloodstream. But if you inhale tobacco smoke, the amount of nicotine in the body doubles.
