I noticed this a while ago. I had a bottle of Evian water, and, when the bottle was sealed, the water wasn’t filled all the way to the top; there was maybe an inch or so of space between the top of the water and the cap. Then, when I opened the water, there was a “whoosh” sound, almost like when you open something vacuum sealed. Then, after the bottle was opened, the inch or so of space was gone, and the water was right at the lip of the bottle.
How could this be? Shouldn’t there be more, not less, space?

Could be as simple as you’re are unknowingly applying slight pressure to the sides. Doesn’t do much when the bottle is sealed. As soon as you open it the bottle deforms a little and causes the water to rise.
