The researchers noted that a singular fart, regardless of time of day, gender, or body size, was between 33 to 125 ml, with a median of 90 ml. The study noted that volunteers on low-fiber diets reduced most of the fermentation gases expelled, lowering their fart volume to 200 ml for an entire day. With that settled, we posed another flatus-related query to Bechtold: If someone farted in cold weather with their pants down, could we visualize the fart similar to the way we see someone’s breath?
