so i posted this in the NFL thread , but i actually looked up and did some research on the relationship between air pressure and temperature . its pretty clear most people havent looked into it , otherwise i doubt this would have become such a huge story
air pressure = air density x temperature . its also known that moist air is less dense than dry air . if the balls were tested indoors in the refs locker room , and then moved outside for the game where it was wet , damp , and 50 degrees . it is impossible for the air pressure not to decrease . impossible .
so it could very well be the case that the patriots balls were approved at the low end of the spectrum (near 12.5 psi) and after being outside for a little over an hour decreased below the legal limit
