In this 1966 episode, 6 1/2 year old Jean Balukas demonstrates her skills at pocket billiards, more commonly known as pool. She is later joined by her 5 year old sister Laura. Information on Jean's fascinating career can easily be found online. For example, from Wikipedia: "At just 9 years old she placed 5th in the 1969 U.S. Open straight pool championship, and placed 4th and 3rd respectively in the following two U.S. Opens. From that early start, Balukas completely dominated women's professional pool during the 1970s and 1980s." And there's much more.
