The concoction is a mostly a combination of two appropriately named foul-smelling chemical compounds, putrescine and cadaverine, which coincidentally are emitted by decaying flesh. Add a dash of methanethiol, the molecule that produces the rotten egg smell, and you’ve got yourself a true stinker. And if you smell like a rotting corpse, says Burks, chances are good that zombies will pass you by for a fresher meal.
“This cologne is an evasive method, which when coupled with zombie mannerisms (as seen in ‘The Walking Dead’ or ‘Shaun of the Dead’), would be effective in avoiding a zombie attack when moving among a zombie horde. One could also wear it when casually waiting out the zombie apocalypse so as not to attract the attention of a roaming horde of zombies,” Burks told NBC News via email.
Burks has been looking into the possibility of using chemistry to survive the zombie apocalypse since 2011.
