9. Industrial Casters, Wedding Cakes, Terahertz Spectrometers, Racing Catamarans
Aired Nov 5, 201521 minTMDb
Heavy-duty wheels are moulded or machined before being fitted with bearings, axles and swivelling metal frames to form industrial casters. Cakes are baked, stacked, covered and intricately decorated for weddings; precision optical and electronic components are calibrated to create terahertz spectrometers; and lightweight composite hulls, crossbeams, masts and rigging are assembled into racing catamarans.
