How do water slides work?
How do water slides work and how are they built? Why do you have to be a certain age or height to go down a water slide? Where does the water in water parks come from? And which is easier to design and build: a water slide or a roller coaster? First we did a little research of our own at Jay Peak Pump House Water Park. (And by “research” we mean “going down the water slides.”) And to teach us more about what’s actually happening when you take your thrill ride, we talked with water slide engineers Songyi Moon and Kelly Sall at WhiteWater West.

Carrots give you night vision! And other things adults say
In this episode: part two of parentisms- you know, the things adults like to say that may or may not be true. So many of these sayings have to do with food: Eating carrots will improve your vision. Drinking coffee will make you shorter. Don’t swallow watermelon seeds or they’ll grow in your stomach. We do a little fact checking on this generational eating advice with Dr. Nusheen Ameenuddin of the Mayo Clinic. And we explore a few other sayings you sent us, like why do parents always say, “Next time” when they really mean “No”? And what the heck does it mean to keep your eyes peeled?

Don’t swallow gum! And other things parents say
We wanted to hear about the conventional wisdom, parenting myths, and downright folksy falsehoods adults pass down to kids, and boy did we get a big response! We heard from over 100 of you about everything from “Don’t swallow gum because it will stay in your stomach forever” to “Slouching will crush your organs” to “If you don’t take a shower after swimming in the pool, your hair will turn green.” In this episode (the first of two), with the help of pediatrician Nusheen Ameenuddin of the Mayo Clinic, we put these “parentisms” to the test! Find out if there’s any truth to the idea that TV will turn your brain to mush, you’ll catch a cold if you go out with wet hair, and it’s dangerous to take a shower during a thunderstorm. Oh, and by the way, this is our 200th episode!!! Download our learning guides: PDF | Google Slide | Transcript

How do axolotls regrow parts of their bodies–including their brains?
In addition to having faces that look like a smiley emoticon, axolotls are as fascinating to scientific researchers as they are to kids because of their amazing ability to regenerate parts of their bodies, including their brains! In this episode we answer kids' questions about these curious salamanders with Dr. Randal Voss, a professor at the University of Kentucky. That lab alone has thousands of axolotls, but these creatures are critically endangered in the wild, where they live exclusively in the depleted and polluted waterways of Mexico City’s Lake Xochimilco. Questions we tackle in this episode: How do axolotls regrow parts of their brains? What did axolotls evolve from? Can axolotls survive out of water?
