As Burt travels around the world he is often confronted with the need to purchase water, which led to an interest in the cost and ecology of bottled water and the history of water in general. In this program we look at how life adjusts to the need for water in different parts of the world, and its chemistry as a liquid, a solid and a gas. We also look at the part water plays in all major religions and a new form of water that was invented in Japan.
