FYI: Is There a Scientific Way to Measure How Bad a Fart Smells?
Popular Science ^ | 9/1/2009 | Bjorn Carey

You’re in luck. For their senior project, two Cornell University computer-engineering whizzes recently built a machine that does just that. 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. Temperature, Clain explains, is critical. The hotter a fart, the faster it spreads. “It beeps faster if it’s a high ranker, and a voice rates it on a scale of zero to nine,” he says. “If it ranks a nine, a fan comes on to blow it away. It even records the noise so you can play it back later.” After a few months of construction, they began field tests. “Well, the sample data wasn’t the entire school, but we definitely tested it,” Salas says.

The contraption could even have use outside of fraternity houses, Clain says, as a biosensor for harmful hydrogen-sulfide-producing bacteria in hospitals. Or dentists could use it to measure oral malodor. They’ve also received some interest from doctors with four-legged patients. “You can test the health of livestock through the quality of their farts,” Salas says. “Smell and sound can tell you a lot about their bowel movements.”

When I was a kid I knew another kid who could fart at will. He was a riot and the most popular kid in the neighborhood. Then one day, after one of his fartapaloozas he accidentally crapped his pants. We laughed at him mercilessly. He never did it again.

I think it was the late (very lamented) George Carlin who observed, “Did you ever notice how your own farts don’t smell that bad? (Farts) That was fairly decent!”

So why bother participating in the thread? The title gives ample warning.

I bet some university could get millions of TARP dollars to do further research.

As part of the dims Cap & Trade legislation, we’ll probably all have one of these gizmo’s installed in our homes and cars.
