The principle of Coca-Cola's ice freezing is "the greater the pressure, the lower the freezing point", and the gas pressure determines the freezing point of the liquid. Shake the coke to let the carbon dioxide out, put it in the refrigerator and freeze it for a period of time. When the bottle cap is opened, the carbon dioxide will come out, and the air pressure in the bottle will become lower in an instant, so the freezing point will rise, from the original liquid to a solid smoothie. Due to the ultra-high speed of the motor, the heat is large, so it can't be stirred for a long time, so the heat is large after grinding, and continuous grinding for a long time will cause the automatic protection function of the motor.
