    Air is a combination of about 80% nitrogen and 20% oxygen. Carbon dioxide is actually more dense than air.

    If you mix vinegar and baking soda together in a container with a lighted candle, the candle will go out since the carbon dioxide produced pushes the air (lighter) up and the carbon dioxide (heavier) stays in the bottom and extinguishes the flame.

    I like Mistie's explanation the best, but I am sure we can't rule out additional factors as well.

    I do agree with the fundamental observation that a C02 filled tube deflates faster than an air filled one. I too always considered C02 as temporary air, and after using it as soon as I get home I always remove all the C02 and replace it with air (not just top off, but deflate and reinflate).
