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?
This is my thought as well. In the end it would be similar to bringing a balloon deep under water, the pressure from all sides would just compress the air inside the to match the pressure outside the balloon. Unless if the rubber had some bad imperfections that were to break under pressure, the balloon should survive.
