There's nothing like a challenge to focus the MythBusters' massive minds! Who will fly into history as champ and who will plummet like a stone? Tune in to find out. In the meantime, Kari, Grant and Tori go to amazing lengths to find out just how dangerous it is to stand too close to the edge of a train platform.
