How can you keep the fizz in 2 liter bottles longer?
Besides, how do I keep my 2 liter soda from going flat?
Leaving the stopper off makes it go flat really quick when it's not all consumed in one day. Best trick, lay bottle on its side after opening. After you open the first time, squeeze the bottle until pop reaches the top. This only works if the 2 liter bottle is half full or more.
Also question is, does squeezing a bottle keep it fizzy?
Squeezing the air out and then closing the bottle will result in a slight vacuum which will allow the smaller bubbles to expand sooner and will take longer to generate a pressure in the bottle. This removes more of the gas and leaves your soda flatter.
Small bubbles caused by shaking help to hasten the escape of the soda's carbon dioxide. Once the the can is opened, all of the gas will eventually escape from the liquid as bubbles, and the soda will go "flat." If the liquid is handled gently, it takes a long time for the dissolved gas to escape.
