S18:E6 Pipe Cleaners, Blue Stilton Cheese, Smart Electric Meters, Telescopes
First Aired: October 18, 2011
Runtime: 21 min
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.
