Water is really cool. It's powerful enough to cut through steel, and yet we drink it and bathe in it. See how water works, from photosynthesis and hydration of the human body to hydroelectric power generation and high-speed water jet cutting. The show follows the path of water from Canada's Athabasca Glacier, through the Colorado River and Hoover Dam, sprayed onto the fertile but dry fields of California, surging inside a 19th Century steam locomotive, and in the clouds above West Texas as we see cloud seeding in action.

Whether it's struck from silver or stacked from cash, there's more to money than purchasing power. From the birth of writing to the pennies that marched into WW2, come explore the root of all evil. This documentary explores the creation of money and coins through time by kings and queens and rogues such as Julius Ceasar and Brutus. Much of the coinage created throughout history has been created for the glorification and edification of rulers and dictators who fancied having their likeness emblazoned permanently on currency for everyone to see. We explore not only the history of coins and money but how it is made. The material used. The secrets behind the coins and currency. The value of coins and currency. Aired date: May 15, 2011
