That's still pumping the blood. That raises the question: does dracula have blood in his arteries and veins that doesn't get pumped, or is all the blood in his stomach?

The coldest temps I've experienced were right about 2F.

It took a good 15 minutes for the color to return to my hands.

Just as a reference, in a biology class in college, we did a pain tolerance test. We stuck our hands in a cooler full of iced brine, temp was measured at 20 degrees. I held my hands in the water long enough that I passed the time limit for safety. I didn't like it, but it wasn't intolerable. The stream? It was intolerable. It felt like my nails were being pulled out by the roots with pliers.
That's effing COLD!

Shyt, I don't know the anatomy of a freaking vampire. I can kill a zombie, werewolf, and a giant spider, but I've never faced a vampire...

Once it freezes like that, I don't imagine it has to stay as cold to keep it frozen.

i have seen pictures of frozen streams and rivers. i know that standing or still water will freeze sooner than moving water. just curious as to how cold it would have to be, that moving water will freeze.

i am sure pretty damn cold!

I do know water needs a "seed", for example a calcium ion, to begin the freezing process, and the more pure a body of water is, the lower of a temperature it can be without freezing, excluding adding salt or another solution that lowers the freezing point.

Rewind to chemistry class, I remember insulating a beaker, melting ice in it until all the water was near freezing, then adding a large ice cube directly from the freezer. Then we stuck a thermometer about a 1/4 inch from the ice cube, and got temps in the upper twenties. The water was still liquid, but below the freezing point.

That's an interesting question, I think there are a lot of variables though, there are waterfalls in Utah that freeze every year, although it rarely gets below zero, but there isn't a lot of water to freeze either... I don't know... I know someone who probably would know but I don't know how to get a hold of him....

According to this, moving water freezes at -55 degrees.

Back to Lake Tahoe, is Lake Tahoe a meteor crater or does anyone happen to know it's origin?

Tahoe is not a crater. I think it was formed as the Earth's crust upthrust over itself. Plate tectonics. If you were to cut the crust from east to west and look at a cross section the western Sierra is like a long ramp up to the summit, and then drops off abruptly on the eastern face. Tahoe is in a large valley virtually on the summit where an enormous scarp sheared off and fell to the east leaving the Tahoe Basin.

That's my uneducated wild-ass guess anyhow.
