Have you ever wondered what’s inside the machines you use so often in your daily life? How does an escalator haul hundreds of people up a slope as steep as mount Fuji? How does a leaf blower generate hurricane-force winds? And how come the tape measure crams sixteen feet of steel into your pocket? Using ultra-realistic computer-generated animation, this episode ‘explodes open’ everyday machines into their individual parts, to reveal their secret workings. Combined with stunning footage from the factories where these objects are designed, built, and tested, this compelling documentary series uncovers the mysteries of machines and how they work.
