Someone made a large public bubble bath in San Francisco on Monday.
Photos surfaced on social media after people walking around noticed white foam nearing spilling out the waters at the iconic Vaillancourt Fountain at Justin Herman Plaza, SF Curbed first reported the story.
Sausalitos resident Kailee Craig took a snapshot of the fountain on her way to work Monday morning in the financial district.
"At first I thought it was snow," Craig told NBC Bay Area.
Another witness, Christopher Hope, walked past the plaza at around 8 a.m. Monday and figured someone dumped what looked like detergent to create the bubbles in the fountain.
"It wasn't until about ten that they shut the thing off to stop the frothing," Hope said. "It was subtle, not [sic] allot of people noticed, but it was hilarious indeed."
The soap didn't make it's way into the walkways and it was contained in the fountain, according to Hope.
It wasn't clear whether the bubbles were a prank or some kind of mistake.
The city of San Francisco Recreation and Park and the Public Works Department didn't respond to NBC Bay Area's request of comment before the publication of this story.
