How It's Made

Season 20 Episode 12: Paper Fans, Walnut Oil, Copper

Decorated paper is cut, folded and mounted on slender ribs to create folding fans. Shelled walnuts are ground and pressed before their oil is filtered and bottled, while copper-bearing material is processed and refined before the finished metal is formed and drawn into useful products such as electrical wire.
