Heat Wave

Yes, folks, it has been hot here in Wichita.

Very, very hot.

The temperature here the past week has had high's in the triple-digits with the latest peak being 109 'F. I think this is the hottest weather in which I have ever been.

Scooter riding has been fine, though, thanks to a jacket that is meshed and allows air to pass through it rather easily. The ride has been short enough that I have been able to stay cool without sweating up a storm. Heat exhaustion/dehydration, though, can be a challenge; drinking lots of water is the norm.

Speaking of water, I have a friend at work who is enough of a health nut that he distills all tap water at home to remove as much of the nastiness as possible. He says, in fact, that every three gallons of Wichita water he distills leave behind a teaspoon or two of, well, nasty-smelling yellow residue. By his account, the tap water from all four places he has lived in Wichita over the past several years have had this residue. By methods I cannot remember he was also able to "test" Phoenix water and found that it did not leave this contaminant behind.

Me, I've never been a big one to be concerned about water purity. After seeing his "vial of vile" though, I was at least slightly concerned. And, unlike some of the other health-nut claims he has made, there is a very easy way to test his assertion! I got a big glass baking pan, filled it with tap water, and have left it a hot, isolated environment (inside my car with the widows cracked) for the past several days and let our record-setting heat evaporate away the liquid. The experiment isn't quite finished yet so I don't have result yet but I'll post them when I get done. (This is another advantage of taking my scooter to work; I can use my car as an oven without having to pay for electricity! Brilliant, I say!)

Regardless of the results, I figure this is probably not a bad thing to do wherever I live. The test is easy and it will give you at least a rule-of-thumb estimate about the quality of the water. Sadly, distillation won't remove ALL water impurities. Anything that boils at a lower temperature than water (alcohol, for example) will also evaporate off with the water. This test really only reveals the particulate contamination in the water. I don't know how carbon filters work (the kind used in most homes, like Brita) so I don't know if they would get rid of this kind of stuff. We have just such a filter and use it often so I may re-run the experiment using filtered water as well just to see what happens.

So, in conclusion:
-It is very hot in Wichita right now.
-Wichita water might be nasty.
-Unused cars left out in the sun all day can double as an oven.
-Science is fun!
