That second article is interesting.
I always figure when God was making up the rules one was “Solids will be heavier than the liquid form”. Until after the first winter and everything in the northern lakes died. I could see a Far Side cartoon of that with God up at the blackboard adding in “except water”.
Super-cool or what!
So can I still use it to chill my beer?
Ultrapure water can be strange stuff. While we think of water as being an electrical conductor, ultrapure water is a dielectric. If there is nothing dissolved in it, no H+ and OH- ions. Run the stuff through plastic pipe will produce a static charge. The biggest use I have seen is the semiconductor industry, where it is used to rinse wafers after etching on the wet benches.
...researchers in Israel have discovered that supercooled water itself will freeze at different temperatures depending on whether it is in contact with a positively or negatively charged surface."Nice, nice, very nice, nice, nice, very nice, so many people in the same device."
Super cooled water, water everywhere, and not one damn ice cube for my drink.
