Brains On! Science podcast for kids

Our stomachs are full of a powerful acid, one that can burn your skin and even melt metal. So why doesn’t this stuff burn a hole through our bellies? We’ll find out how our stomachs protect the rest of us from this acid. Plus, we’ll learn about some of the wildest ways animals digest food and learn about how a serious accident helped us. Don't forget to listen to the Mystery Sound and the latest suggestions for new rooms in our headquarters.

Today we’re stepping into the ring for a battle of the insect world. Molly and co-host Kiaan try to find out if a spider can eat a wasp. They speak with Dr. Paula Cushing. She has been researching spiders for over three decades. Plus, we flip the script and ask if a wasp can eat a spider. Then, Molly goes full game show mode and puts Kiaan in the contestant chair to play Spidey Sense. We also have a brand new Mystery Sound and a big mailbag reveal.

Stickers are everywhere. They label our groceries, cover our car bumpers, and decorate our notebooks. But how do they stick? We’ll zoom in on a sticker to see how a special glue helps a sticker cling to a surface. Plus, we’ll hear about stickers that can help people heal from surgeries. We’ll also find out what kind of stickers Bob collects, and guess a new Mystery Sound.

Guest: Phillip Messersmith, professor of material science and engineering at the University of California, Berkeley.

There’s more to sloths than slowness. They’re great at saving energy, hanging upside down, and swimming! In this episode, Sloth Appreciation Society founder Lucy Cooke stops by to tell us all about these amazing animals. We also get into a sloth mystery: The Case of the Perilous Poop Journey. Luckily, there’s a sloth sleuth on the case. And sloths aren’t the only animals who aren’t in a hurry — a few others show off their slowest skills.
There’s also a Mystery Sound for you to guess. Stay sloooooooooow!
Guests
Lucy Cooke, zoologist and founder of the Sloth Appreciation Society
Jonathan Pauli, UW-Madison Forest and Wildlife Ecology
Dr. Sushma Reddy, Breckenridge Chair of Ornithology, Bell Museum

Have you ever heard of Lake Natron? It’s located in Tanzania, Africa, and, if you believe the internet, it can instantly petrify anything that touches it. Lucky for us, we have a direct line to the Hoax Hunters (aka Sanden and Marc) - they love myths, and they hate getting tricked.
Along the way to saying yea or nay to this stoney phenomenon, the Hoax Hunters speak with Neovitus Sianga. Not only does he have firsthand knowledge of the lake, but he works for African People and Wildlife, where he helps protect the environment around Lake Natron.
We also have a brand new Mystery Sound… and Marc and Sanden start a cleaning service?!?
Guest: Neovitus Sianga
