Adam and Jamie talk trash and crash when they test whether a Styrofoam cup full of soda can be a lethal projectile when thrown from a car at high speeds. Does the cup penetrate the windshield of an oncoming car and seriously injure the driver? Jamie and Adam build a number of soda shooting cannons to see how deadly this myth really is, including a never-before-seen shoulder mounted cannon courtesy of Jamie. On a higher note, Grant, Tory and Jessi Combs (in her final episode with the team) test the classic silver screen cliché of the death defying hang. Are any of these actually viable? Using a helicopter and their wits, the team finds out if these hang times can happen.
