Waterworld USA, 1997
On June 2, 1997, 12 Napa High School seniors took a trip to Waterworld USA in Concord, California, and were planning a dangerous stunt as they ran up to the 40-foot tower and tried to get on the slide at the same time. This was a safety hazard and the lifeguards tried to stop them but they were too late. Their combined weight caused the slide to collapse. This led to 32 injuries as the students tumbled 30 feet to the ground. A 17-year-old girl who suffered severe head and chest injuries passed away as a result.
