Super cooled Water
Last night, well, I guess it was actually this morning ( 00:30 ), I left work and went to my car, got myself situated, and before driving off, I grabbed a bottle of water that was in the cup holder. I distinctly remember shaking it to make sure the water was NOT frozen. I also took note that the bottle was partially imploded; something I would have expected as the temp was down to about 17 o F.
When I opened the bottle, put it to my mouth and tilted it, the unexpected happened. Between the moment of releasing the vacuum that had formed and my trying to drink from the bottle ( about 3 seconds), the water froze to a Slushy consistency. For a moment I was perplexed why I was getting no water in my mouth, and then it slid from the bottom, and it stopped at the neck of the bottle.
I had forgotten that this could happen. I must have sat there looking at it for a good 2 minutes trying to get something out of the bottle, when I thought I would blow some warm air into it. The bottle inflated slightly, and the air passed by the slush, and when I released, I got a face full of slush. I had to laugh at myself all the way after that little incident.
