soda pop theory?

Good point, if you leave it squeezed after putting the cap on.

On a side note…
Have you ever closed a water/soda bottle on a plane(on or off of a tread mill)?
When you land the bottle is “crushed” from the air pressure on Earth.
Or take a bag of chips on a plane - the bag inflates - Yes I am easily amused.
(Just something I have learned in my travels.)
