7. Scorpion’s Tail – USA
Wisconsin Dells is the water park capital of the U.S., and Scorpion’s Tail at Noah’s Ark is its star. This slide starts with a trapdoor. Once it opens, you plummet down and whip through a high-speed looping tube shaped like a scorpion’s tail. It’s over in seconds, but it feels like a wild roller coaster made of water. The slide is transparent, so everyone can watch you twist and scream inside.
