Modern Marvels - Season 17 Episode 13

From hauling our heaviest gear to mastering the tallest mountains, they have been around for centuries, but we constantly improve upon them. Get an inside look at factories where every kind and style of Ropes & Chains are made. We'll get some lessons from a company that trains high-flying workers who depend on rope to do their jobs safely. Learn how window washers, rock climbers and even bungee jumpers safely use the ropes they depend on every day! See dockworkers who rely on ropes around the clock, and pay a visit to the head-spinning factory floors where some of the strongest ropes available are made. See how industrial chain links come to life from just a rusty steel coil and how they're used to anchor massive ships and unload cargo. From parachute cord to shipping lines, from fine jewelry to anchor chains–we'll discover the many uses of today's Ropes & Chains.
