One crazy drop seems like it would be enough, but what about two crazy drops? That’s exactly what happened on Verruckt, which actually means insane in German. In a multi-rider raft, thrill seekers were dropped 17 stories and then sent over a hump and then back down again. At 168 feet tall, this waterslide in Kansas is currently the world’s tallest. However, it’s been permanently shut down after a young 10 year old boy died on the ride.
