was oxygen or air coming out of the guy's helmet, surely it would form as a bubble like in the clip? Due to the vacuum?
I have no expertise in physics so I don't know, but no way was that filmed in a tank.

I mean, what you're watching was filmed in a tank and the background was added via greenscreen.
You know, like in dem movies.
Of course I coould be wrong. It's happened.

....but I highly doubt that it would be visible, what with it being a non-visible gas.
We only see oxygen bubbles in water because it's a liquid - you therefore have a visible surface tension around a ball of gas.
