I am an instructor at a Tech school. Prior to teaching my student how to rivet one of my students thought it would be fun to try riveting after watching a few youtube videos. They wanted a little butt can and decided to throw one together using some scrap pieced during their lunch. They had no idea about rivet shank diameter or how to properly use a rivet gun. Needless to say it became a great wall piece of what not to do as a joke.
