that is not how sprinklers work
Yesterday, I mentioned that I was generally tired of having to explain to people that being out in the cold does not by itself make you sick. I may have also discussed something else, something far bigger of an idea, perhaps on why being right is irrelevant but that's for yesterday not today. This cold myth is one of my personal pet peeves when it comes to people being wrong about something. A perhaps somewhat random and strange second pet peeve about something that is not right is the depiction of how fire sprinklers work in movies and television. Fire sprinklers are almost all temperature-activated and thus are not activated as a group or by smoke. And yet you so often see people in TV and movies somehow activating sprinklers by blowing smoke up to them or be setting off a bunch on one floor by holding a lighter up to a single one. That is not how sprinklers work. Also, windmills do not generate wind.
