The floor drops from under you and, before you know it, you're plummeting down pitch-black tunnels, at high speeds. There are amusement park rides that are so dangerous, most adults are too scared to hop on them.
But these waterslides take the cake. Imagine freefalling, then twisting and turning without knowing what's going to happen next, or shooting through tunnels at speeds up to 40 mph.
These slides are located all over America; however, the most terrifying are in Oregon, Florida and Indiana, just to name a few.
