Again, this is a GoPro video. I know there is a lot of these videos in here but lot of these are so cool... Like this one. They put GoPro inside a Mexican Navy Battleship and the boat is sunk. It's off the coast of Rosarito, Mexico and it's to create an artificial reef. I never saw something like that, it's ten times faster than in Titanic Movie. The water come inside the boat so much faster that you can't do nothing to escape. This is really nice and terrifying at the same time !
