What is the principle of girls licking the tongue of northeast iron railings?

In the eyes of the northeast people, the whole country belongs to the south except for the position of a chicken head. Then, if friends from the south go to the northeast to play, someone will always tell you secretly that the iron railings in the northeast are sweet in winter. Do you believe me? So, curious southerners really had to lick the iron railing with their tongues, and as a result, their tongues were firmly stuck to the iron railing. Alas ~ is it super embarrassing ~ Then the question comes, why does your tongue get stuck when licking iron bars in the northeast in winter?

First, what should I do if my tongue is stuck? Think about how to get rid of this embarrassing scene first! In fact, it's not difficult at all, but if your friends around you are unwilling to help you, it's a bit difficult! So, what about this method? Hot water. Yes, if you don't want to rip your tongue off, the only way to get rid of this embarrassment quickly is to pour hot water. However, if your friends don't want you to get rid of it or there is no hot water nearby, it will be even more sad. So, curiosity really kills cats.

Second, the principle that the tongue will be stuck by the iron railing and knock on the blackboard. The professional answer is below. There are three main reasons why the tongue will be stuck by iron railings in winter:

1, steel pipe temperature is very low, below freezing point;

2, steel pipe and tongue, one is a good conductor of heat, and the other is a bad conductor of heat. When the tongue touches the railing, the heat in the water on the tongue will quickly spread into the steel pipe, making the water quickly freeze. Therefore, if the railing is not made of iron or steel, but a wooden pipe, it will not get stuck.

There are many fine and dense taste buds on the tongue, which are the condensation nuclei of water freezing. If the tongue is smooth without these taste buds, it will not freeze so easily.

Finally, even if it is really frozen, there is no one around to help with the hot water, so don't worry too much. As long as you touch the railing quietly for a while, your body's own heat will gradually melt the ice.
