In the Kitchen : Keep Your Soda Carbonated For Longer

Large bottles of pop are the cheapest way to buy soda. Unfortunately, they usually go flat long before you finish them.

After you open and pour your drink, before re-sealing the bottle give it a squeeze. Closing the bottle after crumpling it will make that soda last much longer.

Carbon dioxide dissolved in water makes carbonic acid. The result is carbonation. When you open the bottle of soda you release the gasses and speed up the flattening process (known as effervescence). When you squeeze the bottle and cap it quickly, you slow the process down again and your soda is preserved for a longer time.
