Modern Marvels - Season 17 Episode 12 Grease
7.90 44 minutes In our lifelong battle to fight friction, Grease–in all its forms–is the unsung hero. Journey deep into places few people ever get to see, to discover the "hidden" uses of one of our most slippery products inside giant machines. We'll also investigate how it's made in a factory in New York, as well as what new advances some are working towards for grease of the future. But in the meantime, we'll witness how it is currently used inside a US Navy aircraft carrier, San Francisco's famous cable cars, elevators and escalators, assembly lines, huge excavators, amusement park rides, and even the Panama Canal. From pig fat to nano-particles… amazing Grease keeps everything rolling along–smooth and fast.
