The one ride that has come to symbolize Action Park and its extreme thrill-seeking was almost never used.
In the mid-1980s GAR built an enclosed water slide, not unusual for that time, and indeed the park already had several. But for this one they decided to build, at the end, a complete vertical loop of the kind more commonly associated with roller coasters. Employees have reported they were offered hundred-dollar bills to test it. Tom Fergus, "one of the idiots," said "$100 did not buy enough booze to drown out that memory."
It was opened for one month in summer 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, and it was widely rumored, and reported in Weird NJ, that some of the test dummies sent down before it was opened had been dismembered. A rider also reportedly got stuck at the top of the loop due to insufficient water pressure, and a hatch had to be built at the bottom of the slope to allow for future extractions.
The ride supposedly reopened a few more times over the years. In summer 1995 it opened for several days before a few more injuries forced another shutdown.
Those who did ride it have said that more safety measures were taken than was otherwise common at the park. Riders were weighed and hosed down with cold water, required to remove jewelry, and then carefully instructed in how they had to position their bodies to complete the ride.
For the remainder of the park's existence, it remained visible near the entrance of Waterworld. The slide was dismantled shortly after Action Park closed and has never been rebuilt.
