Farts come out with varying velocities. While anecdotal evidence circulating on the Internet states that farts travel an average of 10 feet (3 meters) per second, or nearly 7 miles per hour, a scientific determination of fart speed is more difficult to pinpoint.
The average person produces about half a liter of farts every single day, and even though many women won't admit it, women do fart just as often as men. In fact, a study has proven that when men and women eat the exact same food, woman tend to have even more concentrated gas than men.
If a person were to fart continuously for 6 years and 9 months, they would produce gas with the equivalent energy of an atomic bomb.
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.
