Chemical Tank Pressure Vents, Candy Wafers, Food Trucks, Traditional Ropes

How It's Made – Season 27

Precision valves and protective housings are assembled into vents that regulate pressure inside chemical-storage tanks. Flavoured candy mixtures are formed into thin wafers; commercial vehicles are converted into mobile kitchens with cooking, ventilation and service equipment; and natural fibres are twisted into strands and laid together to make traditional rope.
