The Verrückt in Kansas City is officially the world's tallest water slide, standing at a whopping 168 feet 7 inches into the sky. First you'll have to climb 264 steps. Once you're on top, you can see for miles in every direction.
Once you hit the slope, you'll hit about 62 miles per hour (100 kilometers per hour), reaching the end in only 11 seconds! The only downside, it's not open yet, and no official opening date has been given.
