What's inside the machines we use so often in our daily lives? How does a paintball gun fire a pellet 300 feet using just a puff of air? How does a floor scrubber both clean and dry a dirty floor in a single pass? How can an ice machine pump out nearly half a tonne of crunchy cubes a day? Using ultra-realistic CGI 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 program uncovers the mysteries of machines and how they work.
