A Trip To The Laundromat • Earth.com A Trip To The Laundromat

Humans have been tossing things into Yellowstone’s geysers for hundreds of years, unfortunately. Back in the 19th century, reports claim, explorers used to use Old Faithful as a sort of primitive laundromat, throwing dirty clothes into the steaming vent. And later others would drop soap into the opening, in the belief that it would cause an eruption. My word! Photo credit: Yellowstone National Park/Flickr
