The things you learn when your daughter only wants to watch Sponge Bob and all you have to do is troll Wikipedia include learning what happens to a human body when the diving chamber it's in goes from 9 atmospheres to 1 in a fraction of a second:

Subsequent investigation by forensic pathologists determined D4, being exposed to the highest pressure gradient, violently exploded due to the rapid and massive expansion of internal gases. All of his thoracic and abdominal organs, and even his thoracic spine were ejected, as were all of his limbs. Simultaneously, his remains were expelled through the narrow trunk opening left by the jammed chamber door, less than 60 centimeters (24 inches) in diameter. Fragments of his body were found scattered about the rig. One part was even found lying on the rig’s derrick, 10 meters (30 feet) directly above the chambers. His death was most likely instantaneous and painless.

How this has managed to avoid being turned into a movie I never will know.
