Question: is a fart methane gas?
Answer: Farts — also called flatus (say: FLAY-tuss) or intestinal (say: in-TESS-tuh-null) gas — are made of, well, gas! ... Tiny amounts of hydrogen, carbon dioxide, and methane combine with hydrogen sulfide (say: SUHL-fyde) and ammonia (say: uh-MOW-nyuh) in the large intestine to give gas its smell.
