But why? A podcast for curious kids is known for serious answers to silly questions sent

in by kids just like you. But did you know that but why is now a book series?

Our first book, Our Lama's Ticklish, answers questions from real kids about farm animals.

This colorfully illustrated book is perfect for kids ages 8 to 10. And our second book,

To Fish Breathe Underwater, explores the underwater world of the ocean. Learn more at

This is But Why, a podcast for curious kids from VPR, Vermont Public Radio. My name is

Jane Lindholm. Thanks for joining us. On But Why we let you ask the questions and then

we help find the answers. I bet you're a curious kid yourself and I bet you've got lots

of questions in your head. So if you have one you want us to answer, ask an adult, maybe

a parent to help you record it and send it to us. Send it to questions at butwhykids.org

and we'll get to work finding the answer. It can be anything big or small, serious or

just silly. Like why is my hair curly or where does laughter come from? In our last episode

we had a question about how bears are able to sleep all winter long. If you missed it

go back and check out that episode. Today we're going to start off this podcast with a big

question, a really big question. And I want to warn your parents that it might be a little

scary. So maybe they want to listen first and see if it's something you'd like to learn

about. Our question comes from Charlie. He's seven years old and he lives in Kent, Connecticut.

What is the end of the world going to feel like? See I told you really big. Charlie wants

to know what the end of the world is going to feel like. And that could sound kind of scary.

So we're asking someone first who can tell us all about the science. I am John O'Mara.
