This episode of MYTHBUSTERS mixes a killer cocktail of lethal littering and high-flying action movie action. In cup vs. car, Adam and Jamie tackle a tall tale of trash and crash. Can a Styrofoam cup of soda, thrown from a car at highway speeds, penetrate the windshield of an oncoming car and seriously injure the unfortunate driver? It sounds far-fetched, but Adam and Jamie discover how much damage a drink can really do. Tory, Grant and Jessi find out if film ‘fall guys’ can really hang on to the side of a building, Hollywood-style. Just about every action movie has a variation on the death-defying cling, but is it actually viable? The team tests their limits using their wits and a fake chopper.
