One of the most distinctive features of a soda product is its carbonation. Carbonated beverages are infused with carbon dioxide, which provides a bubbly sensation for the soda drinker. Soda manufacturers force carbon dioxide into their beverages at high pressures of up to 1,200lbs per square inch.  When you open a bottle or can of soda, the pressure is released and some of the carbonation will begin to escape. If soda is shaken before opening, the dissolved gas joins the bubbles created by the shaking process. This causes the soda to fizz explosively when opened. Cold soda can hold more carbonation than warm soda. Left opened, any soda will eventually lose its carbonation and begin to taste flat.
