How It's Made

Season 18 Episode 6: Pipe Cleaners, Blue Stilton Cheese, Smart Electric Meters, Telescopes

Soft fibres are trapped between twisting wires to produce flexible pipe cleaners. Cultured milk is coagulated, drained and pierced so the characteristic blue mould can develop in Stilton cheese; electronic measuring components are calibrated inside smart electric meters; and precisely shaped lenses or mirrors are aligned within telescope bodies.
