We're Angus and Jonathon, and we're into really old-school stuff: medieval history! When we're not building castles, playing joust, or reading about knights, we're engineering stuff. Our most recent invention is called a trebuchet, a slingshot-like tool dating back to medieval days that is useful for transporting materials (translation: flinging stuff) long distances. We want to throw out this DragonflyTV question: What trebuchet design will allow us to throw things the farthest?
