Grease

S16, E2: GREASE It makes the whole world go around...and up and down...and side to side. Without it, the wheels of industry and our modern existence would grind to a halt, along with everything else. In this episode of Modern Marvels, we take a close up look - at GREASE. In our lifelong battle to fight friction, GREASE -- in all its forms -- is the unsung hero. This Modern Marvels will take us 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 GREASE is currently used inside a US Navy aircraft carrier, San Francisco's famous cable cars, elevators & 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. It's truly one of the world's most important Modern Marvels.
