August is almost over but there's still time for one more heat wave (which could very well spill over into September.) The "cooling centers" mentioned above are actually recreation centers, community centers, libraries, etc., places that weren't especially conceived of to cool people off but nevertheless are able to do so because of this technological marvel:
Air conditioning has been around since shortly before World War I but didn't become truly commonplace until after World War II. So how did people keep cool during the summers between the wars?
Well, you had to be innovative, I guess. Take these four women, all employees of the St. Paul Daily News. The year is 1936, Minnasota is the grip of a major heat wave, and it's vital that those who work for the paper don't pass out from the heat and stay cooled off enough to report on that day's big story--namely that Minnesota is in the grip of a major heat wave and people have to look for ways to cool off or else they'll pass out. As you might have guessed, this picture came from the Daily News. Sometimes in journalism you are the story. Anyway, as you can see an electric fan is sitting on top of a four-hundred pound block of ice. That struck me as dangerous when I first came across this photo. Ice is actually water, and I was taught at an early age that water and electricity don't mix, one reason why it's wise to turn off the faucet when using an electric toothbrush, or else you might end up zapping the enamel off your teeth. I did some research and found out that water is only conducive to electricity when in liquid form. So what the women in this photo are doing is perfectly safe. As long as the ice doesn't melt. Which it won't because it's got an electric fan sitting on top of it keeping it in a frozen state. It's all perfectly timed. Nothing can go wrong. If by chance something did go wrong, the four women would have again ended up in the paper--on the obituary page.
