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.
