Why and how do cats purr? That’s what Reid wants to know. It sounds like a simple question, but it leads us to a deep challenge: Can we ever understand cats? To find out, we launch a full-scale cat purr investigation. You’ll hear from a puzzled veterinarian, a scientist who studied her cat’s annoying purr, and the author of purring.org, the premier cat purr research website. It’s a purr-fect episode for everyone who’s curious about cats.

More Cheese, Please - Life Lab Pt. 1

Season 8 of Tumble begins September 16 with a special, five-part series called “Life Lab.” Life Lab will explore the incredible power of a new technology you probably haven’t heard of. This technology could solve some of the biggest challenges on our planet, and beyond. But with great power, comes great responsibility. We’ll be asking important questions about whether it could - or should - change our future.
Bonus: Life Lab will be released weekly, for five weeks! After that, we’ll return to our regular schedule of science discovery, every other week.
Help us spread the word! If you can’t wait for all new episodes of Tumble, tell your friends, family, and your teachers to listen along with you. Subscribe or follow wherever you listen to Tumble Science Podcast for Kids.

Tumble Season 8 Starts September 16!

Hear sounds created from images by NASA's James Webb Space Telescope, in this updated episode! The biggest space telescope in the universe had a busy summer, wowing us with incredible images of the cosmos like we've never seen before. But it took a lot of work to get there! Learn about it in this episode, originally released in December 2021.
Hear more Webb sound here. 
Watch the launch here. 
See Webb's first images here.
How do you launch the largest space telescope ever built into space? The James Webb Space Telescope will travel 1.5 million miles away from Earth to help answer some of our biggest questions about the universe. But first, it has to be launched on a rocket - and the telescope is too big to fit on a rocket. So NASA decided to fold it up - and then unfold it in space. How? NASA scientist Knicole Colón and NASA engineer Alphonso Stewart take us on a journey through the world’s biggest origami project.
We have big news to share about Season 8 next week, so keep your ears out for the trailer! 

The Biggest Space Telescope in the Universe (UPDATE!)

Dinosaur Road Trip Adventure

Tumble presents one of our favorite podcasts from RTÉjr Radio: Cereal! 
Deception, Mystery and so much more in “Cereal” RTÉjr Radio’s (not really) True Crime Podcast for all the family. Picture the scene. A brand new TV talent show for kids called “The Novice”. Middle Grade students battle it out to get funding and promotion for their mini company on the national stage. The candidates?
Fergus, an ambitious eco-warrior who’s invented “The Bog Log” a product that turns your poop into compost for your garden.
Xander, a tech whizkid who’s dreamt up the “Homework Helper”, an App that literally does your homework for you.
Brother and Sister Duo PJ and Clara, forced to enter by their teacher in place of detention, have conjured a colour changing Mood Ring.
And Aoife and Katie, best buds for life cooked up the product that gives this podcast it’s name. Crunch Ems; a Cereal bar treat that’s truly healthy and tastes like a dream.
Four perfect products. But all is not what it seems.
When the show goes sideways a tale of blackmail and intrigue is revealed. And who better to chart it in his own podcast but 15 year old Rian, runner on The Novice and budding TY podcast presenter.
Ryan Tubridy cameos as himself, a veteran broadcast adviser to the young podcast host. And amateur sleuth in his own right.
Across 6 episodes Rian takes the listener on a complex journey of discovery to unveil the truth behind the scandal.
Find Cereal on on the RTÉ website, or wherever you get your podcasts.
