My child is learning about the human body and frequently wants to know whether his favorite things work the same way. He asked me if spaceships fart (we've talked about Firetrucks and tailpipes, to his hysterical amusement). I was going to say that spaceships do not, but I'm not actually qualified. I need some expert sources.
When the pressure inside gets too high, do spaceships release the excess air? If they have waste gases that aren't useful or breathable do they vent those into the vacuum?
We all gotta do it sometimes. I mean it's only natural right?
