It traps a treasure of energy on the ocean floor, and confounds scientists still trying to solve why it’s so slippery. We’ll venture inside NASA’s Icing Research Tunnel in Ohio, and then it’s off to Salt Lake City’s Olympic Oval which boasts “the fastest ice on Earth.” Dive to the ocean floor to collect and analyze a unique form of ice called methane clathrates–cages of ice encasing pressurized natural gas. Scientists believe that if only one percent of the world’s ice-entrapped methane could be harvested, it would more than double our current supply of natural gas. Other highlights include the search for extraterrestrial ice and a trip inside the studio of a chainsaw-wielding artist as he sculpts a masterpiece.

It was a science first conjured amid the fiery ovens of ancient blacksmiths; today more than 50% of all U.S. products require some form of welding. Whether via electricity, flammable gases, sonic waves, or sometimes just raw explosive power, welding creates powerful bonds between metal unmatched by any other joining process. From high atop emerging 60-story towers on the Las Vegas strip to oil platforms hundreds of feet below the ocean, discover how welders forge the backbone of civilization. Learn about exciting new applications: how sound waves create bulletproof welds for contemporary body armor; the technologies behind robotic welding systems; and the knee-rattling impact of an explosion weld, the most powerful method of all.
