"But it really couldn't have been all that complicated."

Well, it wasn't really the link I wanted. I simply wanted to show that liquid water has some structural arrangement at molecular level.
My hypothesis wasn't based on knowing that water had some sort of "quasi-crystaline" form- but (to me) this seems somewhat supportive of my hypothesis (which I found out afterwards in "my quest to prove my point":).
But

is pretty good general reference about water- including stuff about supercooled water.
I was actually thinking a couple days ago about a experiment with water which could be done in space. I didn't give it much thought. But first the water would be cold (you could even use supercool water) and water would be very pure (no/as little as possible of gases in it). Also you would start from low pressure- say 1 psi or lower.
Now in micro-gravity the water would be a sphere. And you would place this sphere of water in some box, which could vented to space. You would also want to be able to observe what's going on in the box.
I didn't get much further along than this, nor was I thinking of using supercooled water. But now I think that including supercooled water might be a good idea- just small droplets, so it's easiler to make or get up to station. But I don't know how difficult would be getting it up there- and I'm not even sure supercool water could exist in micro-gravity:)

Btw the http://www.sbu.ac.uk/water/notes.html#fine wasn't exactly right, I meant to give:
