The world's longest waterslide (verified by Guinness) is currently operational, though not open to the public, at Action Park in Vernon, New Jersey. If that sounds like a lot of fun, it looks like it is...for the first 30 or so seconds. Then you start to slow down, then you speed up, then down again, then there's a little bump, then you speed up again, then there's a drop, then it gets real slow. At this point, we are about halfway through. What did you expect? It's the world's longest waterslide.
