Question: When the measure the balls, do they do that by weighing or sticking an air pressure gauge in via a ball pin? My guess and belief is 2 but want to make sure. Because if that is the case, every time you check a ball it is difficult to not let a little air out. Hell, if your an opposing team trying to look good in front of your "detective" GM you could "accidentally" let a lot of air out each time you check.
End this BS frame job and let the NFL world talk about Johnny Manzel or some other inferior team.
they would use a pin, and the amount of air that escapes can really vary.
exponent claims it's negligible, but we've all seen that vid of the ref clumsily letting tons of air out.
weighing the balls is completely unrelated because the amount of gas in the ball doesn't change, disappear, escape, or whatever, it just compresses and decompresses -- but still the same amount of molecules.
psi is pounds per square inch, which is just a measure of force exerted per square inch of surface, not actual weight of any kind.
when gas heats up it expands and tries to basically increase volume.
water, on the other hand, expands when it freezes, which you can see pretty easily in your freezer, but the weight stays the same.
if you want to see any of this action firsthand just blow up a balloon and put it in the fridge for a half hour, and then maybe the freezer and see how it changes.
