All slides I've ever encountered have had an end. This is by far the worst part of the slide, and I think we should remove it.

All you need to make this happen is a decent engine and a half torus of human-sized plastic tubing. Honestly I'm amazed no theme park has done this yet, given the abundance of similar rotating structures they tend to contain.

I'm gonna go ahead and disqualify waterslides, since they're their own thing.
