: How do squeeze to open bottles work?


Im talking about the type when the lid pops off completely when you squeeze it. Is it the air pressure inside the bottle that gets released when you squeeze?

Also as a side note, I really didn’t know which catagory to put this under.

You squeeze the bottle, since you’re compressing it something needs make room for this, so the air compresses untill the pressure inside the bottle increases enough that the lid isn’t strong enough to hold that pressure and pops off.
