Class Action Water Park?

Cannonball Loop

Cannonball Loop, the infamous looping water slide, was only opened for brief periods in Action Park's existence.
In 1983,[48] GAR built an enclosed water slide with a complete vertical loop at the end, similar to that of a roller coaster.[49] The resulting slide, called the "Cannonball Loop", was so intimidating that employees have reported they were offered $100 (equivalent to $299 in 2025) to test it. Fergus, who described himself as "one of the idiots" who took the offer, said, "$100 did not buy enough booze to drown out that memory."[44]

The slide was open for only a month in 1985 before it was closed at the order of the state's Advisory Board on Carnival Amusement Ride Safety, a highly unusual move at the time. One worker told a local newspaper that "there were too many bloody noses and back injuries" from riders.[2] Some early riders came back with lacerations to their bodies, whose cause was later determined to be teeth that had been knocked out of riders' mouths and become lodged in the interior walls.[10]: 12:30 A former Navy physician found that riders were experiencing as much as nine Gs of acceleration as they went through the loop

Insane like complex rides or insane like customers with guns?
