  1. Well, actually, you do breath out air that is about 16% oxygen compared to 21% oxygenated air you breath, so exhaled air is more CO2 rich then inhaled air, there is still oxygen in the air, so he may not kill them. Id be more worried about how hell have opened a passage way into the submarine that the water will utilize afterwards, drowning the men after he leaves

  2. I wondered that too Luke, but they said the submariners opened some valves to let the air in. I don’t know how they managed that without also letting the WATER in, but then, I’m no expert.

    Plus, let’s hope he at least took a super breath mint, you know?

  3. “What was that?!!”

    “It’s Superman. He’s gone to green.”

  4. Submarines *can* open hatches to the water, but they do it on the underside so the water doesn’t come in. The air pressure plus gravity is enough to keep out water. It’s also a fun science principle to show kids B-).

  5. Cool, thanks Cavalier!

  6. But no military submarine (at least to my knowledge) has any ventral hatches that could be utilized like that. And I’m an ex-submariner. 😉

  7. Yeah i know of moonpools (dive pools) or whatever they are called, but think about it, once superman stops breathing air into the submarine, theres a hole that the water will flow into, following the air, and it will flood the sub
