How Aluminum Foil Is Actually Made

How Aluminum Foil Is Actually Made Aluminum was once the most expensive metal on Earth — more valuable than gold or platinum. Napoleon III served his most honored guests on aluminum plates while everyone else ate off silver. Today, you tear off a sheet without thinking and wrap last night's leftovers. How did the rarest metal become the cheapest? And how does a solid block of aluminum become a sheet thinner than a human hair? In this video, we follow the complete journey — from bauxite ore mined in tropical regions, through the Bayer process and Hall-Héroult electrolysis, to the rolling mills that compress aluminum ingots into foil just 0.006 millimeters thick. Along the way, you'll learn why one side is shiny and the other is matte, why aluminum foil was a military secret before it reached your kitchen, and what actually happens when you wrap food in it.
