I went to the Auburn football game today, and decided to buy myself a Coca-Cola. As I was drinking it, I noticed the tiny bubbles in the liquid. Coca-Cola (like any other carbonated drink) has bubbles because when they are produced, carbon dioxide gas under pressure is dissolved into the drink. The process of dissolving carbon dioxide in water is called carbonation. The moment in which most bubbles will appear in the drink is when you open it, because pressure is being released, the liquid cannot hold the excess carbon dioxide and it comes out in "excess bubbles". Carbon dioxide is released into the air once the soda container has been opened, and this process speeds up under warm conditions. Which is why it's a good idea to enjoy your soda with lots of ice when you're drinking it during a very hot summer day!
