Subject: Farts 101
----------
A typical fart is composed of about 59 percent nitrogen, 21 percent hydrogen, 9 percent carbon dioxide, 7 percent methane and 4 percent oxygen. Only about one percent of a fart contains hydrogen sulfide gas and mercaptans, which contain sulfur, and the sulfur is what makes farts stink.

Farts make a sound when they escape due to the vibrations of the r*ctum. The loudness may vary depending on how much pressure is behind the gas, as well as the tightness of the sphincter muscles.
