Answer 11

Sometimes its frozen solid, sometimes it stays liquid, depending on when I put it in there. But here’s the kicker, sometimes when pull the bottle out, it will be liquid, but as soon as open it, it starts to turn into ice, from the top down (it takes a few seconds for the entire bottle to freeze..
In the absence of impurities in the water and imperfections in the bottle, the water can get "stuck" in its liquid state as it cools off, even below its freezing point. We say this supercooled state is "metastable." The water will stay liquid until something comes along to nucleate crystal growth. A speck of dust, or a flake of frost from the screw-cap falling into the bottle are enough to get the freezing going, and the crystals will build on each other and spread through the water in the bottle..
......scientific reason.....
