This doesn't seem right or even possible. The video is pretty cool. 17 story tall water slide that is pretty much a straight drop. And then a bump afterwards...which as I thought about it, you'd be going so fast (~60 mph) that how would you not take flight coming off that hump? And the slide is open-air, nothing to hold you in! Maybe it's the weight of four people in the tube? Too many questions. Opens this summer in Kansas City. Who's in!?
