3. The opened cola solution is in a state of carbon dioxide supersaturation, which is extremely unstable. Under the action of mints, the cola solution will return to a more stable state, thus releasing carbon dioxide. This is because mint contains corn flour, sugar and other fine particles, and its surface is rough, which helps to accelerate the reaction.
