How 2 was a British educational television show which ran on CITV between 1990 and 2006. It served as a modernised "sequel" to a 60’s / 70's series with the same format called 'How'. Each episode started with the presenters sitting around the studio table asking their own question starting with “How” and then taking turns answering these.Subjects of science and history were often covered along with logic and word play puzzles.
