In the second episode of the very first season of The Walking Dead, Rick and Glenn came up with a pretty genius way of blending in with the walkers, using zombie blood and guts to mask their human scent with the scent of death, and completely avoid detection. It totally makes sense, and one chemist believes that scent-masking could indeed be the key to survival, once the dead inevitably rise from their graves.
As we spotted over on NBC News, Raychelle Burks is hard at work on developing a cologne titled Eau De Death, which she considers to be zombie repellent in a bottle. The putrid cologne is actually comprised of two chemical compounds that are emitted from decaying flesh, with the molecule that produces that lovely rotten egg smell being added in for good measure. "This cologne is an evasive method, which when coupled with zombie mannerisms, would be effective in avoiding a zombie attack when moving among a zombie horde," says Burks.
Eau De Death is still currently being developed, as Burks wants to make sure it's absolutely perfect, before going to market.
Check out a fun video from the American Chemical Society below, which talks more about the cologne, and explains why science is as important a zombie survival tool as crossbows and handguns.
If you don't want to wait for Eau De Death to hit the market, you might want to look into the Zombie for Him and Zombie for Her fragrances, which smell of dried leaves, moss and mushrooms!
