I just finished watching Nova on our PBS affiliate. The show was entitled "Hitler's Sunken Secret". It was about heavy water production and shipment in Norway during World War II. Very interesting show, I learned that heavy water in the containers could be determine by the pH. The researchers brought up barrel #26 and found that it did indeed contain 1.1% of heavy water. Later research found that the Germans were just experimenting with the water and were not very close to building a nuclear bomb. Check out more about the show at: http://www.pbs.org/wgbh/nova/hydro/
A somewhat related topic, during the show a scientist showed electrolysis in a flask. I found a site on the internet that allows you to easily break water into hydrogen and oxygen. Check it out at: http://www.theodoregray.com/PeriodicTable/Stories/001.1/
Next week's show about Isaac Newton and his interest in alchemy looks good as well. I am glad to see Google putting some of their wealth to work by supporting the science show Nova. The world needs more scientists figuring out how the universe works.
