Brains On! Science podcast for kids

Hoax Hunters take on the Fresno Nightcrawler

Marc and Sanden are back as the Hoax Hunters! This time they look at the case of the Fresno Nightcrawler. In 2007 a man’s security camera recorded something strange outside his house. It looked like sweatpants out for a walk by themselves, with no humans around. Creepy? Kind of. Unexplained? Very. Join the Hoax bros as they explore this event and learn how it inspired artists, musicians, even the tourist board of Fresno, to embrace the weird stuff around us.

Why are brains so squishy?

Our brains are amazing machines, but they are also very delicate. We have to wear helmets when we bike, skate, or do other activities where we might bang our skulls. Why is the brain so sensitive? Turns out, it’s a soft blob a lot like tofu, but that softness lets it do some pretty important things. Join Molly and co-host Penny as they learn about our wonderful, squishy brains. Plus, Dwayne the Brain joins us and we’ve got a brand new Mystery Sound. Brains On is an independent podcast, which means we rely on listener support to make all our shows.

How do oysters make pearls?

Pearls are shiny little things that look great on a bracelet or necklace. They’re made by shell-dwelling creatures called oysters, but how?

Why do mosquitoes bite?

In this episode, we're tackling all the mosquito questions that have been bugging our listeners. Why do they bite? Why do the bites itch? Is scratching them a good idea? Why do some people seem to be more delicious to mosquitoes? How can we keep them away from us? And are mosquitoes good for the world? The Hoax Hunters also make another hoax-tastic appearance. *Note: if you had a problem with jumbled voices talking over each other, that has been fixed. Just re-download the file or refresh the feed. Appologies - I was trying to shoo away a mosquito. Want to support the show? Join Smarty Pass [https://brainson.supercast.com/]for ad-free episodes, hangouts, discounts and more!
