Wellness fads may come and go, but one beauty trend—using gross unguents to maintain a youthful glow—remains constant. Throughout history, cultures around the world have slathered themselves in concoctions containing everything from crocodile excrement to bird droppings and even snail slime, the last of which was favored by the ancient Greeks and Romans.
Today, mollusk mucous is undergoing a surprising resurgence, as cosmetics companies around the globe use the slime to make skin products. To harvest mass quantities of the clear ooze, snail farmers typically have to kill the tiny creatures. But according to Great Big Story's video below, an Italian man named Simone Sampò invented a snail slime extraction machine—which he has dubbed a "snail spa"—that sprays the critters with secret ingredients, pleasuring them to the point that they secrete their valuable ooze.
Curious how the natural lubricant gets from a mollusk's foot to a well-cared-for face? Watch Sampò's steam machine in action below, as it lulls a bevy of happy snails into producing jugs of slime.
