Now here's a possibly funny one. Today we were discussing the relative merits of having sight glass tubes versus using magnetic and other types of sensors. I kind of "off the cuff", related how an old ships engineer had once told me he could tell the viscosity of an oil by reading it's meniscus in a sight glass tube. Of course, the other guys asked what drugs I was on, and whether I had indulged in lead paint chips as a child.
I really hadn't given it much thought until today, had kind of written it off to "old man brain". But now, "that I are one", and having done some web research, I'm wondering is maybe he didn't have some kind of point. Okay, any takers?
