The Fart Chart — A Flatulence Infographic

What is a fart?  Intestinal gas is an unavoidable part of life.  But do you know what a fart actually is and the methane-mechanics behind it? Below is a great fart chart — a flatulence infographic — with some information about “shooting the breeze” and breaking wind.  You can use it to try and reduce excessive farting or to try and become a gas-passing champion.

Facts About Your Farts

Excuse us for being straight-forward, but farting is the process of passing gas from your intestines and out through your anus. Some will smell, some won’t.  Some will be silent, some will proudly announce their arrival. Flatulence or “butt sneezes” are a varying mixture of air and gases in your digestive system that are produced by digestion. The proportions can change based on diet, illness, and other factors but, typically, nitrogen makes up 59% of the average fart.  Hydrogen accounts for about 21%.  Then you have — approximately — 9% carbon dioxide, 7% percent methane, and 3% oxygen.  Why do farts smell?  Some of the gas leaving your body can contain sulfur-based compounds, such as hydrogen sulfide, and that’s what makes them stink.  Fart absorbing underwear works by targeting those sulfur gases and neutralizing them with an activated carbon (charcoal) layer.

Now what about the frequency and distribution of passing gas?  Do you have below-average, normal, or excessive farting?   Numbers vary, depending on the source, but it’s safe to say the average person will fart about a dozen times a day, for a total of about half liter (half a quart) of gas.  How fast can a fart travel?  They initially leave the basement door at about 11 kilometers an hour (7 mph) but quickly slow down and disperse.

Despite what you might think — and what seems to make sense — the long, loud farts are rarely the smelliest ones.  The majority of farts come from swallowed air which is mainly nitrogen and carbon dioxide — and both those gases are odorless. These also tend to create bigger pockets of gas, which means they create the loudest sounds on the way out.  The other gases in flatulence are created by bacterial fermentation and digestion.  These farts are smaller in size — because there’s less gas — but they contain the smellier gases.  It’s those smaller butt burps that tend to be the “silent but deadly” type of fart.
