I always wondered... can astronauts "swim" in air while on microgravity?
Rooms are always quite tiny so you can always grab something to move without any problems, but if you were in a bigger module and you had nothing at your reach to grab, could you push air as you push water when swimming to be able to move?

Probably launching an object or maybe even blowing air could generate more "thrust" than swimming, but I wonder if there have been any study about it!

I'm no physicist or expert, but given that air is a fluid just as water is, I'd go with yes. Albeit slowly.

Absolutely. Birds do it so well that they can even do it in normal gravity. It's just that humans aren't built to do it well without aid like special clothes.
