Wondering about kitchen sinks and a "tinker's dam".

The double bowl sink that most of us have in our kitchens actually had some design thought put into them that we just take for granted, at least I didn't know.  I bought a book at the flea market a week or so ago called IMPONDERABLES by David Feleman and I have since learned some fascinating things.  It is a wealth of blog ideas but I will try to only use it when, like yesterday, I don't have a thing to say.  But, before we go there, let me remind you to look to the left of the crescent moon tonight to see a comet.

Now, back to the double kitchen sink.  Have you ever noticed that they do not have overflow holes like your bathroom sink does and most tubes?  Why, you may ask?  A couple of reasons.  First, the divider between the two bowls may be lower than the top of the sink, therefore if one side clogs up and over flows, it will over flow into the other side.  That should be the case but not my kitchen sink, the divider is not any lower but there is a slightly higher rim all around the outside to keep any water from getting out onto the counter.  Works the same way.

Now, since we are talking about kitchen stuff, I will tell you what a tinkers dam is and why it ain't worth much.  Back "in the day" if a pot or pan got a hole in it, the people had a person called a tinker to come and fix those pans.  He would solder them up.  To keep the solder contained only where the hole was, he would build a dam out of clay.  After the solder job was complete, the clay dam was removed and discarded.  It wasn't worth a tinker's dam.  I was doubly surprised.  One was to learn what it was and two, to find out it wasn't spelled damn.  Damn, I was wrong again!!!  Sometimes my memory isn't worth a tinker's dam. . . Now, you all have a great day, you hear?
