How do you exactly classify a fart – in terms of wind strength, or how stinky it is? A couple of Cornell University computer-engineering students managed to develop a machine, a fart detector, no less, that houses a sensitive hydrogen sulfide monitor no less, coupled with a thermometer and a microphone. They also came up with the software that is smart enough to rate whatever stink bombs you drop, basing it on the hallowed pillars of stench, temperature and sound. Among the three, temperature is the most critical since the hotter it is, the faster it spreads. This project was deemed interesting and good enough to warrant an ‘A’ from their professor, making us wonder when will it ever get commercialized.
