The Curious World of Springs | Szydlo's At Home Science

This week, Andrew takes us on a journey exploring a seemingly simple object - the spring. From pocket-watches, to the suspension of a vintage car, these simple mechanical objects have a huge number of uses still in our modern world, from storing energy to giving you a smooth drive. There is of course a little bit of action from the blow torch (it wouldn't be a video from Andrew Szydlo without some fire) and lots of interesting mechanical explorations along the way too. Chapters: 00:00 - A spring driven pocketwatch 04:04 - John Harrison and the first chronometer 06:00 - Mainsprings and hairsprings 09:20 - Spring driven toys 15:43 - Investigating a broken mainspring 19:22 - An introduction to metallurgy 23:10 - Experiments with spring steel 30:05 - Leaf spring suspension 34:00 - Helical suspension springs Andrew Szydlo is a chemist and secondary school teacher at Highgate School, well-loved by pupils and Ri attendees alike. He has given public lectures around the country, been featured on TV shows and has become a popular regular face on our channel.
