Is yawning contagious? Could a penny dropping from a building kill someone? These and many other common assumptions are examined in the Discovery Channel's hit MYTHBUSTERS series starring Jamie Hyneman and Adam Savage. Staging exhilarating and often explosive experiments, these special-effects wizards use science--and one very abused test dummy--to answer questions that have been plaguing viewers. This set collects 12 episodes from the show's second and third seasons, including "Cell Phone Destroys Gas Station," "Killer Brace Position," and the ever-popular "Lightning Strikes/Tongue Piercing."
