This should now be displayed as 8th wonder of the world
Water bridge ... over a river ....
Even after you see it, it is still hard to believe!
Water Bridge in Germany.... What a feat!
Six years, 500 million euros, 918 meters long.......now this is engineering!
This is a channel-bridge over the River Elbe and joins the former East and
West Germany , as part of the unification project. It is located in the city
of Magdeburg, near Berlin .
The photo was taken on the day of inauguration.
To those who appreciate engineering projects, here's a puzzle for you
armchair engineers and physicists.
Did that bridge have to be designed to withstand the additional weight
of ship and barge traffic, or just the weight of the water?
Scroll down to check if your answer is correct.

Answer:
It only needs to be designed to withstand the weight of the water!
Why? A ship always displaces an amount of water that weighs the same
as the ship, regardless of how heavily a ship may be loaded.
Remember your high school physics, and the fly in an enclosed bottle project???
Similarly, the super sensitive scale proved that it didn't make any difference
whether the fly was sitting on the bottom, walking up the side, or flying around.
The bottle, air, and fly were a single unit of mass and always weighed the same.
