I question the accuracy of the half a liter per toot number…

I’ve been known to release some mighty trumpeting fanfares from the nether regions the morning after drinking a six pack of Sierra Nevada. But I’d be amazed if even the mightiest and most euphonious flatulations amounted to as much as a liter.

Christ, man - just imagine shoving a pint bottle up yer bum… that’s about a half liter. Even if it compressed to half its size you’d still be cramping big time. (Well, unless yer used to taking things up yer bum, that is.)

A half liter fart is one mighty gust!

And if you do 14 of those a day, you need to cut back on the beans and cabbage.

I read that as 14 barking spiders totaling half a litre, not 500cc each.

Well, of course the volume of gas depends on its pressure. A fart would be under much greater pressure inside the rectum than in the atmosphere. So a liter of atmospheric gas could be squeezed down to a much smaller volume by the rectal wall…

Err… Ummm… Yes, so do I, now that I read it a second time, more carefully. Thank-you, **Padeye**.
