If you fart inside a spacesuit, you might think it would have a special vent to let it out. But the base layer of the suit is airtight, meaning it traps everything inside, including smells. Now, it does have a system that pulls in bad air, like your fart, and traps them in special filters. But it doesn't make the smell go away, meaning for a few minutes, you're just stuck, floating in space, breathing in your own fart.
