3 sources for · 0 against
Two sources discuss whether human gas could propel a person in a contained space, but the available evidence provides insufficient support for the claim.
A compilation of generation rates and chemical compositions of potential waste streams in a typical crewed space habitat, reported in a prior NASA Technical Memorandum and a related journal article, was updated. This report augments that compilation by the inclusion of the following new data: those data uncovered since completion of the prior report; those obtained from Soviet literature relevant to life support issues; and those for various minor human body wastes not presented previously (saliva, flatus, hair, finger- and toenails, dried skin and skin secretions, tears, and semen), but included here for purposes of completeness. These waste streams complement those discussed previously: toilet waste (urine, feces, etc.), hygiene water (laundry, shower/handwash, dishwasher water and cleansing agents), trash, humidity condensate, perspiration and respiration water, trace contaminants, and dust generation. This report also reproduces the latest information on the environmental control and life support system design parameters for Space Station Freedom.

## Question
I am NOT trying to be lewd, but I had a student ask this. Yes, she may have been tongue-in-cheek, but I promised to answer her. And yes, I am trying to keep this as practical as possible.
If and when someone passes gas while in a space station (contained environment in microgravity), would there be enough acceleration to push the person into another position? I don't need direct math, or even biology, but I'd like to return an answer to my student. My suspicion is, physically in a vacuum, yes of course, but on, say, the ISS, would it really direct you?
I am not trying to be lewd, but genuinely want to know the magnitude of order of a fart within the confines of a habitable space station in microgravity to answer her question. If there is literature on it, that's great.
I have great respect for the SE community: so please don't think I'm being silly; I'm happy to have this removed if you find it inappropriate; but I promised a space answer.
Is It Possible To Fart Your Way Across Space?

Don’t tell me you having thought about it. It’s only natural to think about the expulsion of your bodily gas as a rocket launch and then imagine what it’d be like in space. At least that’s why I tell myself. But could it actual propel you? Yes and no.
As PBS’s Space Time explains, your farts could push you through the great abyss. They’d have to; it’s just physics. But even the most prolific farter would be hard pressed to toot their way to anywhere in less than several hundred years. The better solution? Peein’. So just keep that in mind the next time you’re floating just a few too many meters from the ISS and need to dodge a deadly cloud of space debris. And stay hydrated.
