] This is a video taken in 6000 feet of water. An undersea
] robot is sawing a 3mm wide slit (1/10th of an inch ...
] remember that width) in a pipeline. The pressure inside
] the pipeline is 0 psig, while the pressure outside is
] 2700 psi, or 1.3 tons per square inch. Then a crab comes
] along....

This is what it looks like to get sucked through a 3mm hole in the wall of your space craft.
