Everyone knows that the winter in the Northeast is very cold. It can be said that a drop of water turns into ice. People in the Northeast will wrap themselves tightly when going out, for fear that the cold air will take advantage of it.
For southerners who have never seen the cold in the Northeast, they have only heard that in the winter in the Northeast, if you lick an iron pillar with your tongue, your tongue will stick to it.
The reason why some netizens are so curious is that they don’t know why their tongues get stuck when licking iron railings. This is because in winter, the temperature of things like iron is very low, and steel pipes and tongues are good conductors of heat and poor conductors of heat.
When the tongue hits the railing, the heat in the water on the tongue will quickly spread to the steel pipe, causing the water to quickly freeze into ice. So the tongue gets stuck when licking the steel pipe. In fact, the tongue is frozen on the steel pipe.
