Okay Coop. A long time ago, before many of you were born, before brick cell phones, pc's and circuit breakers, houses that had indoor plumbing and electricity, also had fuse boxes. Fuse boxes would interrupt an overload in the electrical system of the house via the "screw in fuse". These little devices, when screwed in, provided an instant disallocation of power to any overloaded circuit. The SIF accomplished this by having the area of least resistance centered at it's core, ie... a tiny piece of metal would melt.
The SIF's were readily available - even at the corner grocery store. Coop would maintain a continuous stock of them, he'd pick some up every time he went to get film for his Brownie camera. I kept them on hand too, as I went with him so I could ask questions about the new Wheatbacks that had just come out. Sadly though, one of our neighbors ran out of SIF's because he had been burning a lot of them up lately. He didn't keep them on hand because he took no pictures and collected no coins. His kitchen circuit went out so he substituted a copper penny - not realizing the penny wouldn't melt like the SIF's. He went to the store, and well, you know the rest of the story.
