I Didn't Know That
Industrial scientists Richard Ambrose and Jonny Phillips find extraordinary facts behind ordinary everyday objects. I Didn't Know That, an action-packed series exposes little-known facts about ordinary items we take for granted. From airbags to teabags, toothpaste to tea, and condoms to crash helmets, each episode is a mind-blowing cavalcade of crazy demonstrations and rarely-heard info about everyday stuff.
Follow presenters Richard Ambrose and Jonny Phillips - two bona fide industrial scientists with an insatiable thirst for knowledge - on their quest to investigate how things are made, what's inside them, how they are tested and how they work.

6)  Magnets 
Did you know that brakes on some vertical-drop fairground rides operate purely through electromagnetic induction? Richard and Jonny head to the fair to investigate, before visiting a scrapyard to demonstrate the incredible weight-lifting capabilities of a magnet powered by just four torch batteries. The guys then check out the magnetic suspension on a Ferrari and look at the future use of magnets in engine-free high speed, floating trains. But that's not all, Richard finds out all there is to know about diamonds while Jonny tackles a gearbox with his angle grinder. Finally, we visit a chip manufacturer famous for creating the Cheese and Onion flavoured chip.
