A safety message from a British in-factory radio station, 1970s, warning that compressed air isn't as benign as you might believe. Clever production, carefully non-specific so as not to give fools any bright ideas.
...Meanwhile, Tam just reported that a survey has over 80% of respondents think there should be a law against "three-parent babies," with mitochrondrial DNA from a third source. This is only useful to prevent certain birth defects, but I guess "tampering with nature" is (in their pea-sized brains) wrong or sinful...in a way that eyeglasses, dentistry, appendectomies or boob jobs is not. Just like vaccination, amirite? (Peanuts, out; correcting birth defects at the start, out; toy guns, right out -- but haul your measelly, mumpsy whelps off to $THEMEPARK and public school? You betcha! It's your divine-issued right!
Here, dimwit, play with a tank of high-pressure air. Don't look directly at the nozzle!*
...Sometimes I'm not sure compressed air has done enough killing. But it would mostly take out the idly curious instead of targeting nitwits anyway, so....
* In the interests of safety and caution, I will point out that my intended-joking reference to laser safety does apply -- but you can do fatal harm with a strong-enough burst against skin. And we're not even going to discuss deliberate and inadvertent projectiles. Compressed air isn't a toy.
