S18:E2 Industrial Wire Ropes, Living Walls, Large Format Cameras, Gemstones
First Aired: September 20, 2011
Runtime: 21 min
Individual steel wires are twisted into strands and wound around a central core to produce heavy-duty industrial wire ropes. Plants, growing media and irrigation systems are combined into vertical living walls; precision bodies, bellows and film holders are assembled into large-format cameras; and rough gemstones are cut and polished to reveal their colour and pattern.
