don't go chasing waterfalls but if you are in china this summer you have to stop and see this one. that's the biggest man-made waterfall in the world and it's screaming off the side of a 22 2 story skyscraper. it plunges from the top floor of the building and it cost more than a hundred bucks per hour to provide electricity for the four pumps that push the water. >> i think this is totally unnecessary. >> people call the cops and say they think there is a plumbing leak and the cops have to come up regularly for this amazing waterfall. >> you would probably have to use the restroom a lot. >> i do love the sound of rain. >> it's hard to run away from the cops when you are on top of the cop car. take a look at this, a man in the back of a texas police cruiser kicked out a window and climbed onto the roof as it sped along the highway. he sat on the top of the car for miles until backup came finally.
