I Didn't Know That

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.
