TL;DR: No. The half-life of hydrogen-sulfide (one of smelliest constituents of a fart) reacting with the oxygen in the jar from just your fart is 12-37 hours. The article gives an example of a particularly potent hypothetical fart that would only retain any distinguishable odor for 9 days tops.

So if I farted into a vaccum sealed bag... I could save it then?

Sadly, the fart itself comes with oxygen included

So i have to design an attachment to take oxygen out of the fart before sealing it? I better start watching some TED talks this could be some work.

There is a reasonable amount of oxygen in farts? Really?

[–] [email protected] 20 points 2 days ago* (last edited 2 days ago) (1 children)

4% of a fart is oxygen, according to the article, which is enough to react with all of the hydrogen-sulfide, since 1 mole of oxygen is enough to react with more than 1 mole of hydrogen-sulfide (H₂S makes up around 1% of the total volume).

What if we add oxygen absorbers in the jar as well ?

[–] [email protected] 15 points 2 days ago (1 children)

Persumebly not but there is oxygen in the air, usually.

Dammit I wanted to breathe in only farts

What about the other odor producing compounds? From wikipedia:

Hydrogen sulfide, methyl mercaptan (also known as methanethiol), dimethyl sulfide, dimethyl disulfide and dimethyl trisulfide are present in flatus.
