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? LISTEN NOW | DOWNLOAD |
