Summary

Metal is amazing. It can be super strong like a steel beam. Or super flexible, like a copper wire. Humans have been obsessed with metals of all kinds for a very long time. This is part one a three-part look at how humans have used metal throughout history. Molly and co-host Ava are joined by Dylan Thuras, co-founder of Atlas Obscura, to look at how Earth got metal in the first place, how humans first found and used this stuff, and when we started making primitive tools with it. Plus, Marc and Sanden have some problems unpacking the new Brains On library. All that and a Mystery Sound! Guest: Dylan Thuras, co-author of The Atlas Obscura Explorer's Guide to Inventing the World. Want to support the show? Join Smarty Pass to listen to ad-free episodes or donate!
