Ultrapure Water Corrosion
I was told by a sagacious professor of chemistry that ultrapure, de-ionized water will corrode stainless steel. You can't blame me for wondering why. I always pictured water as a passive solvent. But "H2O" in its purest form can indeed be corrosive. Copper, glass, plastic, and stainless steel will all slowly lose molecules to the pure liquid. Highly insoluble metals, i.e. pure tin, are the only materials immune to water's alluring properties. But, if the gaseous oxygen is removed from the water before it is stored, you're ok to use whatever typical storage container you want. I still don't know why this happens, but I imagine it has to do with huge osmolarity forces coupled with the chiseling action of electrons on dissolved O2 molecules.

Call Me a Pour Sport
Yes, at last we poured the foundation and we are so happy with how it turned out. The stars really aligned for us. It was delivered and mixed for us, which saved an unthinkable amount of work. A family friend came over and helped us figure things out. And the surface is about as smooth as we could have hoped for. Except, of course, for a little decoration provided by my sister and mom.

Global Warming
If people are genuinely convinced about global warming, why aren't more people moving up to Alaska? I don't believe in it, so I'm happy where I'm at. But it seems to me that those who do believe in imminent, dramatic increases in temperatures would go somewhere cold to beat the rush. They might expect the property values in Alaska to go through the roof when it happens.

Man's Best Friend
I have always loved dogs. It's not a good time for me to go and get one, but maybe in a year or two. So I have posted a new poll hoping to get some input. There are few options to choose from, but there should be at least one you like. Comments would be acceptable for a write-in candidate.
Also, please note that the breed name "German Shepherd Dog" is correct nomenclature: the "Dog" part is not redundant. It carries over from the translation of "Deutscher Schäferhund." Whereas in the "Australian Shepherd," the "dog" part is only implied. In Germany maybe they call it "Australier Schäfer." Anyone know? I love dog trivia.
