How Giant Ships Get Into the Ocean: A Shove and a Prayer

It would be so much easier if giant seafaring vessels could be built on the water. But that's impractical, silly! Which is why, instead, we build those humongous ships on dry land, get them as close to the water as we can, give 'em a shove and hope for the best. And by "the best," I mean "huge splashes and boats coming dangerously close to tipping over." [Reddit via Geekosystem]
