1. The principle of turning coke into smoothies actually contains a little knowledge of physics, that is, "the greater the pressure, the lower the freezing point". The pressure of gas determines the freezing point of liquid, which is the same as the boiling point of boiling water on the Qinghai-Tibet Plateau is less than 100℃.

2. Shake the coke vigorously to let the carbon dioxide out and put it in the refrigerator for a while. When we open the bottle cap, the carbon dioxide inside will come out, and the air pressure in the bottle will drop instantly, so the freezing point will rise, changing from the original liquid to solid sand ice.
