This BBC Web site is absolutely packed with interactive features and cool facts about human senses. Created as the online companion to a recently-aired BBC science documentary series, this Web site offers a fun way to explore the five senses and the human brain. A set of quirky tests help visitors determine whether they are supertasters, learn about their personalities via the foods they crave, or explore the relationship between age and the smells that recall childhood. The site also includes an interactive tour of the brain and an excellent quiz-like tutorial on the major systems of the human body. Each episode in the series has a summary page and an informative factsheet.
