Why does a shaken coke explode with a flick of your finger?

This capacity exceeds the capacity of the bottle. When shaking the coke bottle, the carbon dioxide gas in the liquid will be dispersed throughout the bottle, breaking the balance. Flip the coke bottle with your fingers, and the gas in the bottle will expand rapidly, because the volume of gas will increase with the increase of temperature. It will exceed the bearing capacity of the bottle, and a flick of your finger will cause the bottle to explode. Coke refers to a carbonated drink, which is sweet and contains caffeine, but does not contain alcohol.
