No, methane has no smell. Mercaptoethanol is added to it (and propane) to make gas leaks detectable.

Methane has no smell, that’s why it’s so deadly. I think your thinking of sulfur gas.

I thought methane had a smell because of farts. Are farts even made of methane?

Farts are flammable due to methane. Sulfur is more of an eggy smell. Leaking car batteries are a pretty potent example. Mountain homes with well water often have H2S (hydrogen sulfide) in higher amounts. This is what makes the water smell like absolute crap and taste awful.

Some farts contain methane. Not all.

Per Wikipedia: Not all humans produce flatus that contains methane. For example, in one study of the faeces of nine adults, only five of the samples contained archaea capable of producing methane

Hydrogen sulfide is the fart smell. But methane is what makes farts flammable ETA: upon further research I’ve learned that farts can travel about 10 feet per second, or approximately 6.8 miles per hour. Just wanted everyone else to know.

No no, that’s the rotteneggfart you’re thinking of. The smell of ass is largely derived from volatile fatty acids derived from bacterial decomposition of proteins and complex carbohydrates.

Same as shit, basically.
