Voices: How do we make sound?
We are very vocal about this episode, and that's because it's all about voices. We look into how our bodies produce sound and talk to a voice recognition expert. And we find out what's happening when helium enters the equation. Plus, humans don't have the voice market cornered -- what about other animals? We'll drop in on a few creatures and find out how they make sounds too. All that plus a brand new Mystery Sound and berry delicious Moment of Um. Today's episode is sponsored by Quip (getquip.com/brainson), KiwiCo (kiwico.com/brainson), and Bombas (bombas.com/brains). You can support Brains On at brainson.org/donate
Roller coasters: from dream to extreme
How do roller coaster designers go from dream to reality? World-renowned roller coaster designer Alan Schilke tells us how he does it. Also -- why do some people feel sick or dizzy after riding them? And how do coasters make you feel like you're floating? Plus: a tricky mystery sound and a Moment of Um that answers the question, "How do boomerangs come back?"

Finding your way without a map
If your GPS suddenly stopped working, would you still be able to find your way? In this episode we'll teach you tricks and tips to navigate on your own. We'll explain how compasses work and we'll tell you who helped move north to the top of the map. Plus, we'll meet a navigator who goes on long journeys using only traditional Hawaiian navigational techniques and we'll stop by a pitstop for some amazing animal migrators. All that and a Moment of Um on why diamonds are so rare and so valuable.
