Astronauts have such cool jobs!  They get to blast off in rockets, experience micro-gravity, and see Earth from a whole new perspective.  But how does someone become a NASA astronaut?  We asked spacesuit designer Pablo de Leon to help us find the answer!

Shells come in so many amazing shapes and sizes -  spirals, sand dollars, sundials, ones that whirl around, ones that twirl around, ones that twist to the side and some that even look like cookies! Our listener Lily had a great question about these shapes, and Mike Sanchez, a Naturalist at the New Mexico Museum of Natural History and Science, helps us get to the bottom of this twisted subject!

Throwing up isn’t fun, but it happens to everyone. Sometimes we vomit if we’re sick with a virus or an infection – and other times, it happens because we’re feeling dizzy or carsick. But do other animals barf too? Like snakes? We asked wildlife biologist Laura Kojima to help us find the answer.

You might have heard a rumor that snails have a big reaction when you pour salt on them. But curator Tim Pearce from the Carnegie Museum of Natural History wants you to know that it’s cruel to do so. And he’ll tell you why!

If you fold a sheet of paper just right, you can create a paper airplane that zooms through the air! But how do you make sure that your plane zooms across a room instead of nose-diving into the couch cushions? What makes a good paper airplane? We asked physics grad student Angie Huerta to help us find the answer.

Have you ever screamed when you saw a spider in the house? First of all, don’t be scared, that spider isn’t looking for you. But second of all, did you wonder if the spider even heard you? Most of us haven’t gotten close enough to a spider to see if it has any ears at all. We asked spider expert Paul Shamble to explain how spiders hear.

Oobleck is a mix of cornstarch and water that can act like a solid or a liquid. On its own, it’s gloopy and squishy, but if you squeeze it, it turns into a solid ball in your hand! So what would happen if oobleck fell from the sky like rain?  We asked meteorologist Ginger Zee to help us find the answer.

We’ve all seen cartoon images of a mousetrap loaded with a big wedge of delicious cheese, but is that what mice actually like to eat? Maybe they like spaghetti, or tacos, or chocolate pudding. We asked veterinarian Kate Pritchett-Cornett what we should serve next time we’re having a family of mice over for dinner.

Paper is made out of trees! But… how? Those tall, leafy, shade-giving beauties in your backyard don’t look anything like the piece of white paper coming out of your computer printer. We asked forest expert and educator Sanford Smith to help us find the answer.

About 60 miles above Earth is a line where our atmosphere ends and space begins.  That boundary is called the Karman line.  Of course, rockets that astronauts take go much farther than that.  But just how far from earth have astronauts gone?  And what do they need to bring for the trip?!  We asked spacesuit designer Pablo de Leon to help us find the answer!
