[00:00:00]Imagine a smell so bad that a single drop can evacuate an entire neighborhood. Meet thioacetone, the foulest smelling substance on Earth. In 1889, German chemists accidentally spilled a tiny amount during a routine experiment. Within minutes, the odor spread for half a mile. People on the street started fainting and vomiting, causing total panic. Scientists described the odor as rotten eggs, sewage, burning rubber, and rotting meat combined. Why does it hit so hard?

[00:00:32]Because our brains associate even microscopic traces of sulfur with danger, like decay or toxic gas. And oddly enough, the more it is diluted with water or air, the worse it smells.

[00:00:44]It doesn't fade. Today, it has zero practical use, which is why it is never mass-produced.

[00:00:50]>> A stench so foul it's right off the funkometer. I dare say Fry may have discovered the smelliest object in the known universe.
