Why aren't all farts flamable?  Don't tell me they are cause there have been times when an entire batch was nothing but duds.   TIA and I will listen off the air.

Not all farts are high in flammable methane.  Many are primarily bubbles of swallowed air or are high in CO2 (ex. from beer), which will not ignite.

Coors Light causes high amounts of methane. Or so I've been told.
