Adam and Jamie get feisty with a bar fight fable while Kari, Grant and Tory investigate a ballistic material mystery from history. Forensic scientists have supposedly discovered that you'd be worse off having an empty beer bottle smashed over your head as opposed to a full one. Sounds counter intuitive, no?

Meanwhile, Kari, Grant and Tory challenge the concept of a leather cannon. According to historical documents, ancient Swedish and Irish armies used animal hides to build their cannons. There is no written record of how successful these leather cannons really were, so the testing was rather explosive.
