Off-topic discussion. Wanna talk about corsets, duct tape, or physics? This is the place. Detailed discussion of any current-season TV must be whitefonted.

Third useful thing? I think you're golden until Tuesday.
well, they were very small things.
Lee, I'll do your productive things if you do mine. It will be like Wife Swap, only with chores.

Hmmm. Why do I get the feeling I'll be vacuuming up cat hair, regardless?
Nope, it's all about grading poetry explications, bay-bee!
You do realize that's not necessarily better, right?
Video of supercooled water: [link]
Freaky. I've heard of it but have never seen it. It's water that's been cooled to 21 degrees Celsius (-6F).
Wiki on supercooled water: [link]
A liquid below its freezing point will crystallize in the presence of a seed crystal or nucleus around which a crystal structure can form. However, lacking any such nucleus, the liquid phase can be maintained all the way down to the temperature at which crystal homogeneous nucleation occurs. The homogeneous nucleation can occur above the glass transition where the system is an amorphous—that is, non-crystalline—solid.
Water has a freezing point of 273.15 K (0 °C or 32 °F) but can be supercooled at ambient pressure down to its crystal homogeneous nucleation at almost 231 K (−42 °C).1If cooled at a rate of the order of 1 million kelvins per second, the crystal nucleation can be avoided and water becomes a glass. Its glass transition temperature is much colder and harder to determine, but studies estimate it at about 165 K (−108 °C).2 Glassy water can be heated up to approximately 150 K (−123 °C).3 In the range of temperatures between 231 K (−42 °C) and 150 K (−123 °C) experiments find only crystal ice.
Now I think I must see water glass....
OK, let's do the fortune cookie bed thing with the second paragraph above:
Water has a freezing point of 273.15 K (0 °C or 32 °F) but can be supercooled at ambient pressure down to its crystal homogeneous nucleation at almost 231 K (−42 °C) - in bed!

Sorry. That amused me. I hope it amused at least one other person....
Aw, that sucks aurelia. I hope you have a much better tomorrow.

I'm on vacation, and in the last week, I've probably been 10x as productive as I am at home, if you don't count the time when I'm at work. If I'm at church or at someone else's home, I feel urges to do dishes, wipe counters, sweep, even mow the lawn (ok, the last two probably only for family or close friends, but still). At home, it's like pulling teeth for me to do any more than basic maintenance, or to do even the basics any earlier than absolutely necessary. In short, I think this is a great idea, and want to join a club.
