How to Keep Drinks Carbonated

Joseph Priestly introduced the first carbonated beverage in 1767, and it immediately became popular because of its sparking, effervescent nature. In 1886, Coca-Cola introduced the first cola drink, and the world's love affair with the soft drink was born. Today your local grocery store sells hundreds of varieties of soft drinks, but the technology to keep the drinks fizzing has not progressed as rapidly. For over 120 years, soft drink lovers have had the same question: How do we keep carbonated drinks from going flat?

Skill level:
Moderately Easy


  1. 1

    Keep the soda sealed before you are ready to drink it. Opening the soda allows the carbonation to escape into the air no matter how tightly you close the container.

  2. 2

    Ensure that the soda has been standing upright in a cool place before you open it. If the soda was laying on its side, it may fizz over and let most of the carbonation escape all at once. Warm soda will also lose more of its carbonation because the molecules in warm soda move faster than in cold soda, which allows the carbon dioxide to escape at a faster rate.

  3. 3

    Fill a glass with ice when you are ready to drink the soda. Pour the soda slowly and at an angle, allowing the soda to run down the inside of the glass. This will reduce the amount of carbon dioxide from the soda that escapes into the air.

  4. 4

    Close the container as tightly as possible if you do not drink all of the soda. Keep the container cool and drink the rest of the soda within 1 to 2 days to ensure that it is still carbonated.

Tips and warnings

  • Do not bother to squeeze the plastic bottle to remove the air once you have opened it. Boyle's Law of Pressure proves that once soda is opened, carbon dioxide will escape from even a tightly closed and squeezed plastic bottle.
