Kentut merupakan gas boleh terbakar, kerana kandungan methane dan hidrogen yang boleh terbakar, dan keduanya terdapat dalam kentut.
Flatus is flammable, because methane and hydrogen are flammable gases, and they are both found in flatus. Less known, is that lighting a match will remove the odour from a flatus. The odour in flatulence comes from hydrogen sulphide (which comes from foods in people's diet). Upon lighting a match the hydrogen sulphide will decompose to form water (vapour) and sulphur dioxide. Removing the hydrogen sulphide also removes the odour. <ref>{{cite web | url = | title = Fighting Farts with Fire, by Wendy Zukerman | accessdate = 2008-6-6 | language = english | format = html | source = Webblog}}</ref>
== Composition of flatus gases ==
[[Nitrogen]] is the primary [[gas]] released during flatulence, along with [[Carbon dioxide]] which is present in higher quantities in those who drink [[carbonated beverages]] regularly. The lesser component gases [[Methane]] and [[hydrogen]] are [[flammable]], and so flatus containing adequate amounts of these can be [[Fart lighting|ignited]]. However, not all humans produce flatus that contains methane. For example, in one study of the [[feces]] of nine adults, only five of the samples contained [[archaea]] capable of producing methane.<ref>{{cite journal| author=Miller TL| coauthors=Wolin MJ, de Macario EC, Macario AJ| title=Isolation of Methanobrevibacter smithii from human feces| journal=Appl Environ Microbiol| year=1982| volume=43(1)| pages=227–32 |pmid=6798932 |pmc=241804 |doi= |url=}}</ref> Similar results are found in samples of gas obtained from within the [[rectum]].
