That’s How You Put A Ship In The Water [Video]
I like ships. I don't know an awful lot about how they work so I have often wondered how do they get those big things built in the water? Well they don't build them in the water, they do construction in a dry dock, then comes the fun part.
Sliding a huge multi-ton ship into the water. It would be really scary to be on board when this happens. Check out the big splash these big boats leave in their wake.
