So I know I promised to write about Capri Sun this week, unfortunately it is going to have to wait for a least another two weeks. Sorry.
Yesterday, at work, I was out on the football field with one of the gym teachers. We were watching our students run a half mile because they were being obnoxious. During the course of our conversation he used a common idiom and we talked about where it found its origins. I remember finding it a fascinating bit of history, however I can no longer remember what the phrase was, or what the history of said phrase was. The experience was almost entirely stripped from my memory by the what followed.
The teacher asked me if I knew the meaning behind the saying, “Near but it ain’t aplomb1.”
I told him that I could guess given that I knew what aplomb meant2.
He asked me if I knew how you measured to see if something was aplomb. I told him with a plomb-bob. He then asked me if I knew why they were called plomb-bobs. I told him I didn’t.
Traditionally, plomb-bobs were made by hanging pieces of lead from a string. You let it hang straight down and you can tell if whatever you are making is straight up and down. Now if you remember back to your last chemistry class the atomic symbol of lead is Pb. The reason for this? In Latin lead is called “plumbum.” Thus the plumb-bob. During the height of the Roman empire plumbum was all the rage. It was very malleable, relatively easy to extract and refine from ore3, and most importantly it didn’t rust. So when the Romans went about creating a system of pipes with which to deliver water to their cities lead was an obvious choice.
Unfortunately, for the Romans, they were unaware of a little thing called lead poisoning. Some scholars theorize that the fall of the Roman Empire may have been hastened, if not caused, by lead poisoning.
But none of this was really all that mind blowing. Here is what got me. The original sewage pipes were created out of plumbum, and what do we call people who work on our pipes today?
Plummers. Ka-boom.
