S19E12: Navajo Rugs, Crude Oil, Kaleidoscopes, Titanium Dental Implants

Wool is cleaned, spun and dyed before being woven by hand into traditional Navajo rugs. Crude oil is brought to the surface and separated from water and gas for transportation; angled mirrors and coloured pieces are enclosed inside kaleidoscopes; and titanium is precision-machined, cleaned and sterilized to create threaded dental implants.
