A fart is gas that escapes from a body and it is a combination of gases (nitrogen, carbon dioxide, oxygen, methane, and hydrogen sulphide) that travels from a person's stomach to their anus. The fart is created when a person swallows too much air or eats foods that the human digestive system cannot digest easily, and when gas becomes trapped in their stomach. A fart is art! I kid you not!
A fart is made by all the microbes which live in our intestines. The microbes break down the paste from our stomach into the useful ingredients which help our body, and a whole load of waste, which is, quite frankly our poop. The breakdown process in our stomach produces complex sugars. Normally these complex sugars end up in the large intestine where bacteria tries to break them down and hydrogen and carbon dioxide are formed.
Another term for microbes is bacteria. These bacteria can also produce methane in our stomachs. Bacteria eat the food we swallow. The stinky fart gas comes from those bacteria.
The carbon dioxide and methane gases are actually produced during food breakdown in the large intestine. When excess gas is sensed in the rectum, a signal is sent to the brain, which ascertains if it's a good time to release the gas.

Some people say that as methane itself is also rich in hydrogen, the same element that may one day power fuel cell cars, so, we may one day be powering our cars with our own. This is not really correct as although methane contains the hydrogen molecule it is bound-up inside the methane molecule. It is much more likely that methane in a fart could be theoretically used to power cars by prufying it and compressing it when it would be called CNG or Compressed Natural Gas. CNG is in use right now powering cars, especially in Norway but elsewhere as well.
One man who is capable of producing methane lays claim to the distinction of being the world's only performing flatulent. Methane production in a fart has been claimed to be hereditary so not all people create it.
I have never done a chemical analysis of a fart, nor measured relative atomic masses of carbon, hydrogen, oxygen, nitrogen, etc. The closest I've come to empirical evidence is seeing someone else perform demonstrations of Boyle's Law and Charles' Law, both of which are specific cases of the ideal gas law.
The writer of this article has been known to be unable to stifle his amusement after witnessing a funny fart: Thanks, Steve for this article refreshing subject, and indeed I know that you have been guilty of the odd funny fartyourself! Go there to that site now! Its it all about the fun of the fart video.
