Surely, if not all of us were taught in childhood that in no case should you touch metal with your tongue in the cold. Some "enthusiasts" may have even independently checked why this should not be done. And yet the main "childish" question for the majority remained unanswered: why does the tongue even freeze to metal at sub-zero temperatures?

This is actually a very interesting physical question! The whole point here is in the process of heat exchange. The fact is that metal is an excellent conductor of energy, including heat. Therefore, it heats up quickly enough and cools down just as easily. Heat exchange occurs when two touching objects have different temperatures. Actually, a metal product in winter in the cold will be seriously cooled, but the human tongue under normal conditions always remains warm.

Actually, these "normal conditions" are rapidly changing and the tongue quickly cools down as soon as it comes into contact with the metal. In the cooling itself, there is nothing harmful to a person in this case, however, there is saliva on the tongue, which guaranteed to freeze, turning into ice, as soon as the temperature of the skin on the tongue begins to lose its positive temperature. As a result, the tongue can freeze very tightly to a metal product, which a person deigned to touch in this way. Purely theoretically, this will not happen if the tongue is completely dry, however, it is almost impossible to check this, since it is almost always very wet.

As a result, the moisture content of the tongue is also superimposed on the special porous structure of the cover of this organ. The ice penetrates into the micro-crevices and fetters the tongue so that any attempt to break the ice shackles can result in a serious and very painful injury. In order to get out of the insidious trap, it is necessary that someone from the surrounding ran for a teapot with warm water and gently poured the tongue and metal on it. The metal will heat up, the organ will melt and peel off by itself.
