Cold that you can hear

Finally got cold here, winter, deep cold, a sound changing freeze.  Squeak, squeak, crunch is the sound of shoes on the snow. Wind over the taut electric lines adds a low string bass hum.  Jets overhead roar with sound amplified by the clear cold.  Recent weather from here.

Interesting activity:  Did you know that if you have a horseshoe magnet that has lost its magnetism it can be re-magnetized? I didn't either. Process involves wrapping 12 or 24 wraps of enameled copper wire around the magnet leaving wire hanging off of either end then touching one loose end to the positive terminal and the other to the negative terminal of a 12 volt (car or truck) battery. Touching as in zap, zap, zap a micro-second at a time, because the wire gets very hot very fast.  If for some reason you try this wear insulated welding gloves. The more you zap, the stronger the magnetism gets -- up to the original power of the magnet, I guess.  Did I mention the wire becomes red hot?

I wore leather gloves over thick rubber gloves, messin with 'lectricity calls for caution in my world.

Can't think of an interesting family story at the moment.  Ok, not completely true, the Easter when we got chocolate eggs filled with candy in our baskets and blue tile.  There is something -- dim, way back.  Will have to work on it.
