# Why will crushing a water bottles keep the water in fizzy condition? [duplicate]

Everybody is talking only about CO2.

• Hi and welcome to physics.SE! When you ask a question, please try to make it accessible to readers who may not immediately know what you are talking about. In particular, please don't only put the question in the title, but repeat it in the body. Who is this "everybody" you mention, why are they "talking only about CO$_{2}$", and what has this to do with your question? The more specific you are and the more context you give, the better answerers will be able to give precisely the answer you are looking for! – ACuriousMind Aug 21 '17 at 11:20
