Janitor Stumbles Upon Floor Bubble in School Gym, Then Sees What’s Underneath

This find led to a convoluted chain of discovery and excitement as they found old photographs, old yearbooks, alumni autographs, and other memorabilia from the school, dating as far back as the 1950s. It became crystal clear that the bubble was not a result of a prank, but a consequence of decaying buried items, and the methane gas it produced while decomposing.
