(Randomly discovered whilst watching back-to-back episodes of How It's Made on the Quest channel while ironing my shirts yesterday... it's a thrill-a-minute lifestyle here, you know... )
It's scarily addictive, especially if you have a geeky inclination like me.
Perfect to watch while ironing shirts too, as you can time your shirt's progress against each segment, and both the programme and the ironing are boht basically about creating a more efficient production line. Same applies for polishing shoes...
