At about 3:30PM on the 2nd of June 1997 students from the senior year at Napa High School in California were visiting Waterworld USA in Concord. They decided to enact a traditional prank, by “clogging” a waterslide with as many students as possible. It was a lighthearted stunt that been carried out in previous years with no adverse consequences. This year, however, it would prove to be fatal.
