Every sport is filled with moments that call for actions and reactions in a split-second. This episode breaks down a number of those moments. We examine precisely how much time an NFL quarterback has to make a pass, and how he copes with the intense pressures after the snap. We break down every millisecond of a baseball pitch, and reveal that a batter has two-tenths of a second to make a decision. We analyze two NFL wide receivers, to determine if they are actually faster than lightning. Sport Science uncovers the vision secrets of the NBA's best passers - it's all about peripheral vision. We test to see if an ice hockey goalie can really have reflexes as fast as a cat, and we examine the reaction times in the fastest sport on earth: Top Fuel drag racing.
