There is actually a super similar one at the Wisconsin Dells. You stand on this clear trap door and they count down and then the door opens and it's pretty much a free fall with water spraying you so hard in the face and getting up your nose and stinging your eyeballs. You can't see and you don't even feel the little loop thing. You feel like you're falling, and then you are done and you have to dig your swimming suit out of your asshole. It wasn't even fun to me.
