‘PBS Space Time’ Host Gabe Perez-Giz Explains How He Calculated the Weight of a Fart for a Recent Episode

In a recent video, PBS Space Time host Gabe Perez-Giz explains how he calculated the weight of a fart for his episode about the plausibility of farting one’s way to the Moon. To squeak out his best estimate, Perez-Giz looked at a paper published in the New England Journal of Medicine that measured the gas makeup of 10 people’s farts and the ideal gas law to find a workable average fart composition.
