from my friend David: an
video taken in 6,000 feet of water. An undersea
robot is sawing a 3mm wide slit (1/10th of an inch, or
about the thickness of two CDs ~ remember that
measurement) in an undersea pipeline. The pressure
inside the pipeline is 0 PSI while the pressure
outside is 2700 PSI, or 1.3 tons per square inch. Then a crab comes along....
