I Didn't Know That - 1x02 - Glue- Followmy.tv

In a bid to find out all there is to know about glue, Richard and Jonny recreate the classic ‘flying man’ wallpaper paste TV ad by gluing Jonny to a board and dangling him from a crane above a pool of water. Find out how chairs are tested by robotic artificial human bottoms that each clock up 3.5 million ‘sit downs’ a month. Then Jonny slices open a plasma TV to see what’s inside, while Richard looks at the technology of modern bank notes and the bacteria they harbor. Finally, ever wondered how the writing gets into seaside rock? We show you how.
