How 2 is a world-famous children's programme dedicated to science and general trivia. Originally aired in 1966 under the title How, TVS brought it back to life in 1990. Though the name was changed, the format stayed the same: Three presenters sit around a table, and ask rhetorical questions such as "How way-out can I be?" (about pivoting and moments), "How can failure lead to fortune?" (about the invention of the Post-it note) and "How can lighting blow your socks off?" (the question says it all!).
