Reply to comment by tallerthanu17 in TIFU by opening my waterbottle at work by MoonTearChild

Same thing happened to me once, also on a plane. I actually switched to wide mouth bottles after that...

It’s because the air pressure on a plane is less than on the ground, but the sealed bottle stays the same pressure, so upon opening, it will violently depressurize

So is a solution to prevent this to keep opening and closing the bottle during ascent? Get the pressure inside decreasing in steps.

I’ve had this happen once and have avoided it since by slightly opening the bottle (where some pressure gets released) and leave it like that through takeoff and then do it again for landing.
