At the Hoover Dam, you can actually pour water straight up into the sky. No lie. And there’s a cool little experiment you can do that will prove it. All you have to do is open up a bottle of water, reach out over the edge of the dam, and start pouring it out. Instead of trickling down its concrete wall it will reverse course and shoot up into the air.
The Hoover dam is one of the main tourist attractions in the eastern US. The size of this dam is gigantic, but the size does not matter because the sight that you might see is too spinning for you to consider the size. If you visit this place, do some self experimentation. Bring a bottle with yourself, stand on top of the constructed area, open the bottle and try to pour the water down. You will be amazed by the sight that the water instead of going down, will move upwards. The scientists have a rather satisfactory answer to this mystery. The answer is that the construction of this dam is such that the flow of air becomes way too strong.
The flow of air upwards trough the edges pushes everything upwards, hence nullifying even overcoming the gravity. It is not just the water; throw anything down there and it will flow upwards but make sure that nothing strikes your head because the push from the air is too damn strong.
