 Forged in 1890 the victory bell served on campus to signal dismissal from classes before being moved to Clyde Williams Field and subsequently to Jack Trice Stadium.To go along with the installation of the new video board and sound system prior to the 2011 football season, a tornado siren is sounded after touchdowns, defensive stands, and other big plays.While the tornado siren is a new tradition, it is one that numerous Cyclones fans have asked the Iowa State athletic director to implement for many years, especially since the Colorado-Iowa State game of November 12, 2005, when a tornado touched down in Ames and sirens were heard throughout town during what normally would have been pregame activities.
