Shades of James Watt. A tea kettle boiling on a cake of ice? Impossible! But such a phenomenon actually occurs if the vessel contains liquid air instead of water. The temperate of liquid are is 310 degrees below zero in comparison with which ordinary ice is "hot". One of many fascinating experiments in Basic Science demonstrated in portraying the "Story of Air" in the Hall of Science at a Century of progress in Chicago. This Basic Science exhibit is presented through cooperation of Union Carbide & Carbon Corporation, world's leading pioneer in development of chemical products.
