A San Francisco school made an awesome discovery recently -- there's a 100-year-old time capsule hidden in one of the building's walls.
In 1910, the city's mayor placed a copper box in the wall and covered it with the school's cornerstone. The school has no official record of the time capsule, and they only recently learned about it because former student John Weidinger was researching the Cleveland Elementary School's history for its 100th anniversary. Just one sentence in a September 19, 1910 newspaper article mentioned the box.
The cool thing is no one has a clue what's inside that box. John hopes the mayor left a letter, but tells the San Francisco Chronicle, "A lot of kids think there are gold coins in there."
San Francisco district's chief facilities officer David Goldin says they'll try to uncover the time capsule over the two-week winter break, but it won't be easy. The cornerstone is surrounded by a mural and they also don't want to damage the original cornerstone in order to get the box out.
"I think it's kind of an interesting story in a universe of tough times," he said. "That's what mysteries are all about. Life is fun for these kinds of things."
