They used to have a program called "Hot Dog," on TV. Joann Worley of "Laugh-In" fame was the hostess. They showed all sorts of manufacturing processes, such as how they put toothpaste into the tubes, how they make crayons, and others. It was a Saturday Noon kid program, but I ate it up; it was well-done and one of my all-time favorite programs along with Twilight Zone, Star Trek, etc.
