Is There A Scientific Way to Measure How Bad A Fart Smells?


Yes, there is! After learning in class how breathalyzers work, Robert Clain and Miguel Salas assembled a fart detector from a sensitive hydrogen sulfide monitor, a thermometer and a microphone and wrote the software that would rate the emission.

A 'slight perturbance in the air' near the detector sets it to work measuring the three pillars of fart quality: stench, temperature and sound. The contraption could have use outside of fraternity houses as a biosensor for harmful hydrogen-sulfide-producing bacteria in hospitals. Or dentists could use it to measure oral malodor.
