Like - when a pumpkin is tiny, it obviously had little air inside of it, and then when it gets bigger, there is lots of air inside of it. I have looked all over and haven’t really been able to get a clear answer…? Some people say it diffuses through the walls of the pumpkins, but I can’t really envision air diffusing through a wall inches thick and full of water.

I guess the same question applies to other hollow fruits, such as some melons or peppers?
