Our 200th episode is SUN-sational!

For our 200th episode, we get an up close and personal look at the sun. 


There’s no better way to celebrate our 200th episode than with our own shining star: the sun! In this episode we speak with Dr. Nicola Fox, who leads a team of NASA scientists that sent a probe to collect data and zoom by the sun. We also hear some great listener suggestions on what new planet could be added to our solar system. We even get a chance to check in with The Sun and her weekly broadcast, That’s Hot.

Our 200th episode wouldn’t be complete without a visit from some of our favorite pals: Bob, Gungador, Harvey and Elevator! Of course there’s a new Mystery Sound too. And the Moment of Um comes just in time for mosquito season, because it answers the question: Why do we itch?

Thank you so much for helping us make 200 episodes! We could never have done it without your questions and encouragement, and we can’t wait to make 200 more!


How NASA's Parker Solar Probe Will Survive the Sun

How far can a cloud travel?

Can the same cloud you see travel halfway across the world?


We’ve all played the “what does that cloud look like” game. Maybe you saw a bunny… or an airplane… or a unicorn. What if that same cloud also be seen by someone in a far off continent? That’s what a listener in Minnesota wondered. He wanted to know if the same cloud he saw in a park near his house could also be seen in Africa.

We talk to Deanna Hence, one of our favorite weather experts, and she tells us about how clouds travel. We also dust off the Zoom Ray to learn about what is inside of a cloud. And have you ever noticed the similarities between cloud types, like cumulonimbus, and magic spells from Harry Potter? Well, we have, and we made a game out of it!

We also have a brand new Mystery Sound for your guessing pleasure (or torture) and a Moment of Um that answers the question: Why do pugs have such scrunchy faces?  

Totally Slothsome: All about sloths

Slow moving sloths and their perma-smiles have captured the heart and minds of people everywhere. Find out what makes this slowest moving mammal tick. 


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, and a Moment of Um: Why do ostriches stick their heads in the ground?
