Like, say you had a grain silo or some theoretical structure that would allow you to fill the structure as high as you wanted, full of balloons, all inflated with regular air, not helium.
Is there a point where the balloons’ collective miniscule weight would be enough to pop the balloons on the bottom? Or would they just bounce/float on top of each other forever and ever?
Is this question assuming air pressure and gravity loss at higher altitudes, or is it assuming that the full structure would have a consistent air pressure and gravity? If so, would it be from sea level?
A standard party balloon is around 3 grams if I had to guesstimate, so you could probably figure out how much weight it would take to burst a single balloon, and divide that by 3 grams to get the number of balloons. The main problem with that is the varying amounts that buoyancy and gravity would provide the upward or downward forces.
