When we were finished at the Cat Show we decided to check out the insulator show across the way at the Fairgrounds. Insulators are what holds the wires on the telephone pole. Insulators are made of ceramic and glass. They are nonconductors. There are lots of people who actually collect these things. The show at the fairgrounds had about twenty collectors. They were there selling their conductors as well as talking about them. There were a few men who were nice enough to give us some insulators to start our own collection. A word of warning though...... Insulators are made of glass. They are breakable. Don't drop them on a tile floor in your front hall. They will not survive.
