Guy Inhales a Gas That Makes Him Sound Like Satan
YouTuber Cody'sLab has gained notoriety for his scientific experiments that he does to explain things that might not be easy to explain.
One of his newest videos has him inhaling sulfur hexafluoride which is known as the Deep Voice Gas. It makes his voice pretty deep, but he takes it a step further.
He takes it up a notch and uses perfluorobutane, which makes his voice so deep you can barely understand it.
The gas isn't suitable for humans "except under an approved protocol."
