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.
That reminds me of when I was a kid, farting in the bath. As I saw the bubbles coming up to the surface, I wanted to catch them.
So I took whatever plastic container I could find around the bath - most likely the cap of a shampoo bottle - submerged it, and held it close to my butt when I felt the next fart coming.
I succeeded in catching some of the fart in the cap. Then I claimed my prize by sniffing directly from the cap. It was so much worse than any fart I've ever smelled.
As a true scientist, I've repeated the experiment on a few later occasions, and without a doubt : bath farts captured in plastic containers smell much worse than normal farts.
I remember sitting in the hall during school as a second grader taking to a friend. I said, "I wonder if you farted in a balloon if it would float." A teacher overheard me and scolded me about it, for some reason.
That was the perfect opportunity to teach the first step of The Scientific Method. The next step was the Hypothesis - what do you think will happen, based on the scientific knowledge you already have?
Then you have to Plan The Experiment, which in this case, would probably really energize the students' brain power. They'll LOVE figuring out this experiment. I would bet that EVERY student would be engaged in this one.
It's the Doing The Experiment that might be problematic, and end up with the teacher explaining themselves to the School Board: "All I can say is, it seemed like a good idea at the time. I guess you had to be there."
I think its because while its under water it doesn't have a chance to diffuse into a larger volume of air -- normally farts are pretty dilute by the time it makes it to anyone's nose.
$1k / jar and brought in $100k... so that's 100 jars total. Maybe a little extra in case of an accident during shipping. So why did she need to fart 50x per week? Shit, that would be $2.4 million per year of she could actually sell that.
So the way I see it, she was farting in a jar 50x per week but only selling 2 of them... that's not a business, that's a fetish she managed to squeeze a whiff of money out of.
methane does not have a smell. most hydrocarbons don't. that's why they put smelly stuff (mostly thiols, which are very smelly sulphur compounds) into butane, gasoline, etc.
How do you preserve a sunset, or a child’s laughter? How do you preserve the feeling of a first kiss, or the flavor of your mom’s hug? How do you preserve the memory of your lost love, or the fish that flew away? How do you preserve the anxious feeling of your first ritual death match in the ring of eternal fire, or a crisp autumn day?
Based on my experience with GCMS, if you fart into some activated carbon, you might be able to store it for a long time. To release the smell you'd heat your "sample" up to about 250°C, which you could do in a hot oven or maybe stovetop burner
