5. Corkscrew Carving, Roaring Springs, U.S.A
Plummet down a 32-inch narrow tunnel that lets you drop 38-feet per second from a trap door– You’ll need to hold your breath, so you don’t breathe in the water rushing past your head before the ride takes you across an entire 360-degree loop. In the end, after you’ve surely screamed your head off, you’re dropped into a chlorine pool.
