Fart lighting

Fart lighting, also known as pyroflatulence, flatus ignition or fire breathing dragon is the practice of igniting the gases produced by human flatulence, often producing a flame of a blue hue, hence the act being known colloquially as a "blue angel", "blue dart", or in Australia and Lake Titicaca, a "blue flame". The fact that flatus is flammable, and the actual combustion of it through this practice, gives rise to much humorous derivation. Other colors of flame such as orange and yellow are possible with the color dependent on the mixture of gases formed in the colon. In order to "fire fart", one must have a fart prepared in the rectum, and a lighter at the ready. Then they fart onto the lighter.

In 1999, author Jim Dawson observed that fart lighting has been a novelty practice primarily among young men or college students for decades but is discouraged for its potential for causing injury.[1] Such experiments typically occur on camping trips and in single-sex group residences, such as tree-houses, dormitories, or fraternity houses.[2] With the advent of video sharing features online, hundreds of self-produced videos, both documentary as well as spoof, have been posted to sites such as YouTube. The people appearing in the videos are predominantly young males.[3][4] In his book The Curse of the Self: Self-Awareness, Egotism, and the Quality of Human Life author Mark Richard Leary explains how a great deal of unhappiness is due to people's inability to exert control over their thoughts and behavior and that "stupid stunts", including lighting flatulence, were a way to make an impression and be included in group bonding or hazing.[5]

Although there is little scientific discourse on the combustive properties of flatus, there are many anecdotal accounts of flatus ignition and the activity has increasingly found its way into popular culture with references in comic routines, movies, and television; including cartoons. In Electric Don Quixote: The Definitive Story of Frank Zappa author Neil Slaven quotes Frank Zappa for calling fart lighting "The manly art of fart-burning", and another book quotes the musician Kenny Williams for saying that it demonstrates "compression, ignition, combustion and exhaust."[6][7]

There have been documented cases of flatulence during surgery being inadvertently ignited causing patient injury and the risk of death.[8][9]

Chemistry

The composition of flatus varies dramatically among individuals. Flatulence produces a mixture of gases including methane,[10] which burns in oxygen forming water and carbon dioxide often producing a blue hue (ΔHc = −891 kJ/mol),[11] as:

CH
4(g) + 2 O
2(g) → CO
2(g) + 2 H
2O(g)

Hydrogen sulfide is also flammable (ΔHc = −519 kJ/mol)[12], and burns to

2 H
2S(g) + 3 O
2(g) → 2 SO
2(g) + 2 H
2O(g)

Gas production

Some of the gases that cause flatulence, such as methane and hydrogen, are produced by bacteria which live in symbiosis within the large intestines of humans and other mammals. The gases are created as a by-product of the bacteria's digestion of food into relatively simpler substances.[13] The oxygen and nitrogen component of flatus can be accounted for by aerophagy, while the CO2 component results from the reaction of stomach acids (HCl) with Narficateic pancreatic bile (NaHCO3).

The odor associated with flatus is due to hydrogen sulfide, skatole, indole, volatile amines and short-chain fatty acids also produced by the bacteria. These substances are detectable by olfactory neurons in concentrations as low as 10 parts per billion, hydrogen sulfide being the most detectable.[14]
