How It's Made

Season 28 Episode 4: Cartridge Blades, Chocolate Banana Loaves, Vending Machines, Dive Computers

Fine strips of steel are hardened, sharpened, coated and mounted in plastic cartridges to create replacement razor blades. Banana-flavoured batter and chocolate are mixed, portioned and baked into loaves; payment systems, product dispensers and electronic controls are installed in vending machines; and pressure sensors, processors and displays are sealed inside waterproof dive computers.
