No. 雖然屁既成分係有甲烷,喺CH4 is low % by mass of carbon同burn under excess oxygen既時候,喺會發生complete combustion which is an exothermic reaction,產生熱。但唔好唔好唔記得,屁中甲烷只佔大約7%,而有成21%係hydrogen黎,test of hydrogen都知會有pop sound,因為氫具可燃性,火箭燃料都係同樣原理。氫可form flamable mixtures in air sith wide range of concentrations。其實4%嘅氫喺有氧同火種嘅情況下已可點燃,21%已算了。所以,你燒屁,有可能引火自焚,高濃度嘅屁更可引發大火!!小心小心!!
