Brains On is coming to a city near you!

In our final look at metal, we explore how metal wires changed the world. Once humans figured out how to send little blasts of electricity through metal, we quickly developed lots of uses for this. One was a new way of communicating called the telegraph. Join Molly and co-host Ava as they team up with Dylan Thuras, co-founder of Atlas Obscura to learn how people laid hundreds of miles of wire in hopes of sending messages across oceans. Plus, the new Brains On Headquarters is having an opening ceremony, and there’s a brand new Mystery Sound to guess!

Guest: Dylan Thuras, co-author of The Atlas Obscura Explorer's Guide to Inventing The World.

How metal wires changed the world!

Humans have been fascinated by metal for thousands of years. But it took us a long time to master making things with metal. In this episode we go back in time to learn how Japanese swords were forged, how swings were used to make thin metal wires and why steel cables saved so many lives. Molly and co-host Ava are joined by Dylan Thuras, co-founder of Atlas Obscura for part two of this deep dive on all things metal. Plus, Marc meets some talking boxes and there’s an all new Mystery Sound.
