I just realized I set tge original group wrong here, so I've changed the
follow-up.

The EVA incident should result in a ISS research project. While inside
the station, but wearing a suit, get some water injected into helmet in
various ways, and fully document how it behaves and test various
techniques for the astronaut to deal with that water.

(for instance, wouldn't rotating head as quickly as possible cause water
blobs to leave face and be thrown towards the helmet where surface
tension should keep it there ?)

Interesting question. Honestly, not sure. Not sure you could rotate your
head fast enough to overcome the surface tension (it's not much, but on the
other hand, if the layer of water's thin enough, you won't be able to spin
enough of it off.)


Repositioning the clean air pipe so that the air movement it creates
would cause water blobs to stay away from face.

etc etc.

This is something they can't really test on the ground since you need 0G
and the ISS is a perfect test facility for this.


Except... you might have trouble getting this past the human experimentation
boards. There's still a very high risk of aspirating water into the lungs,
something I'm sure they'd want to avoid.

That said, still not a terrible idea.
