I know it sounds crazy, but its true!
"US astronaut Chris Cassidy and Italy's Luca Parmitano were less than an hour into a planned six-hour outing when Mr Parmitano reported what seemed to be water inside his helmet."
Coolant for his spacesuit started leaking into his helmet. They believe he had between 1 to 1.5 liters inside his helmet. He couldn't see or hear, barely able to speak, as these blobs of water covered his eye, ears and mouth. He had memorized how to get back into the station, so he worked his way back to where he could get back into the airlock. I imagine that was fun trying to do that without being able to see. Finally back in the station, the other astrnauts frantically worked to get his helmet off. Once off the water floated away, and he was ok.
If that had been me, there would have been more then water in my suit!
