How to Weigh a Fart | Space Time | PBS Digital Studios

The video tutorial explores the concept of weighing a fart by applying the ideal gas law. Dr. Michael Leavitt's research indicates that daily fart volume ranges from half a liter to two liters. By assuming the ideal gas law applies, the mass of a fart can be calculated if the average molecular mass is known. The gas composition varies by person and diet, with a density of about one gram per liter. A practical example assumes an astronaut produces one liter of gas, equating to one gram of mass over 24 hours. The video concludes with a per-fart mass analysis, estimating between 0.05 and 0.1 grams per fart.
