So yeah, as the title says. If you fart do you become lighter because you loose mass or does the loss of buoyancy make you heavier ?
You get heavier, totally anecdotal evidence on my part but I’ve stepped on the scale in the morning, let a glorious one rip, and the number went up by 0.1.
I am not saying that I gained 0.1 lbs, just that afterward the scale rounded it up instead of down.
Sounds like solid scientific research to me, I will now carry this nugget of information as an absolute fact.
Sharting makes you lighter for sure
Farts are mostly particulate. So, you’d be lighter.
m… mostly?
Please discuss this with your doctor.
On top of the fact that the gases have lower molecular weights than air, they are also at 37°C or 310K ie ~5% lighter still.
I think “mostly particulate” would have to cause visible exhaust fumes 😅
Makes me muuuuuch lighter. At least that’s the feeling in my belly!
That is less pressure, not weight.
Methane is lighter than air, so farting makes you heavier.
But not in any measurable way.
Methane is lighter than air
Objection! ;-)
This comparison is not relevant, unless you take in as much air immediately as you have just pressed out.
Would you now please show us how you do that?
If it’s lighter than air, it’s lifting you while it’s inside of you…
If it’s not there, it’s not lifting you, and you’re heavier.
Think of a balloon that is so old it doesn’t rise anymore. It just stays neutrally bouyant. In this case it’s even less than that. It is a completely and totally negligible amount of difference. But while holding a fart you’re technically a very shitty balloon.
Unless you are in a vacuum chamber, then it makes you lighter. Also you would be dead.
It depends on how pressurized it is. And clearly farts are pressurized.
As a homogenous blob, you would become lighter and denser.
I think, you get lighter from the thrust, and the loss of those rarefied substances also reduce your mass.

A balloon full of helium has more mass than a balloon without helium, but less weight en.m.wikipedia.org/wiki/Mass_versus_weight.
Methane weighs more than nitrogen (70% of atmosphere); you lose weight and mass. Molar mass of nitrogen 7; methane 16.

This guy farts.

But he doesn’t let it weigh him down.

Methane is lighter than air. Methane is indeed ~16 but nitrogen has atomic number 7, molecular mass ~14, and the molecules are N2, so ~28.

At room temperature methane is lighter than the atmosphere on Earth’s surface, not heavier.
However, pressurized in your body it may he heavier. I see no studies measuring this.
