Title: Why does licking ice stick to your tongue?

In the hot summer, licking ice cubes is one of the ways many people relieve themselves from the heat. However, many people find that their tongues become "sticky" when they come into contact with ice, which can even cause minor frostbite. What is the science behind this phenomenon? This article will analyze this phenomenon from a physical and physiological perspective, and attach hot topic data in the past 10 days for reference.

1. The scientific principle behind licking ice cubes and causing them to stick to your tongue

When the tongue comes into contact with ice cubes, the adhesion phenomenon is mainly caused by the following two factors:

1.temperature conduction: The surface temperature of the tongue is about 37°C, while ice cubes are usually below 0°C. When the two come into contact, the moisture on the surface of the tongue quickly cools and freezes, forming a thin layer of ice that "glues" the tongue and the ice together.

2.Surface wettability: The surface of the tongue is usually covered with saliva, and the moisture in the saliva freezes quickly at low temperatures, further exacerbating the adhesion effect.

To avoid getting your tongue stuck, it's recommended to lick the ice cube quickly rather than touching it for a long time, or to choose ice cube molds with a coating on the surface.

3.Use a straw: Drink iced drinks through a straw and avoid direct contact with the ice.

4.Pay attention to oral health: Excessive consumption of ice cubes may damage tooth enamel, so it is recommended to consume it in moderation.
