How It's Made S30 E12
Aerospace Fasteners, Cactus Pear Puree, Lab Reactors

Specialized alloys are formed, threaded, heat-treated, coated and rigorously inspected to produce fasteners capable of withstanding aerospace loads. Cactus pears are cleaned, peeled and processed into a smooth purée, while corrosion-resistant vessels are equipped with mixers, valves, sensors and temperature-control systems to become laboratory reactors.
