Mike shows how porcelain from a spark plug can break glass with ease. Then tries to do the same with a rock. Why doesn't he just use the hammer? Because this is not a video on how to break glass with a hammer. Why does he talk like a caveman? For fun and to explain it in a simple manner. No, you don't need a vise to recreate this.
