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!

Tumble Presents: Cereal

Tumble Presents: Cereal

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.

The Science of Bubbles

The Science of Bubbles

Why do bubbles pop, and why do bubbles have shadows? We’re in double bubble trouble with two listener questions. Luckily, Dr. Bubbles is here to save the day! We’ll find out how a normal, everyman physicist named Justin Burton became a superhero bubble scientist, on a quest to make a scientifically proven recipe for giant bubbles. Along the way, we’ll discover the answers to our listeners’ bubbling curiosity.

Hear from the inventor of edible bubbles, Li Wei Tan, in a bonus interview episode available on our ad-free Patreon feed! It’s available for just $1/month when you pledge to support Tumble at

We’ll have free resources about bubbles on the blog on our website,

This episode is sponsored by MEL Science. Check out their awesome science boxes at

Make sure to use the offer code "TUMBLE" at checkout for 60% off your order. 

Here is Dr. Bubble’s Giant Bubble Recipe, courtesy of Emory University:


1 liter of water (about 2 pints)

50 milliliters of Dawn Professional Detergent, which is available online (a little over 3 tablespoons)

2-3 grams of guar powder (or guar gum), a food thickener sold in some grocery stores or available online (about 1/2 heaping teaspoon)

50 milliliters of rubbing alcohol (a little more than 3 tablespoons)

2 grams of baking powder (about 1/2 teaspoon)


Mix the guar powder with the alcohol and stir until there are no clumps. Combine the alcohol/guar slurry with the water and mix gently for 10 minutes. Let it sit for a bit so the guar hydrates. Then mix again. The water should thicken slightly, like thin soup or unset gelatin. Add the baking powder and stir. Add the Dawn Professional Detergent and stir gently, to avoid causing the mixture to foam. Dip a giant bubble wand with a fibrous string into the mixture until it is fully immersed and slowly pull the string out. Wave the wand slowly or blow on it and enjoy the physics of giant soap bubbles!

Results may vary based on humidity.

Music Meets Science

Music Meets Science

What happens when a scientist is also a musician? For Barbara McClintock, the combination may have led the way to a Nobel Prize in genetics. Science historian Jocelyn Bosley tells us the story of Barbara’s remarkable life, and how her experience playing banjo in a jazz band (yes) helped her discover “jumping genes.” This is a very musical episode, with special guest jazz banjoist Mick Sullivan of The Past & The Curious! We highly recommend his history podcast. Want to hear more from our interview with Jocelyn? Listen to our exclusive interview episode on Patreon, available to those who pledge just $1 or more a month! We have more resources to learn about Barbara McClintock on our website, as well as links to Jocelyn’s podcast, Science! With Friends. Just go to!

The Tale of The Hungry Koala [ENCORE]

Tumble returns with all new episodes starting January 22! We’ll have stories about fossils, telescopes, and baby falcons getting into big trouble.

How does a koala eat eucalyptus leaves? Eucalyptus is toxic to most animals, but they’re a koala’s only food. In this episode, we look past the cuddliness to discover how koalas manage to chow down on the Australian tree species. Biologist Michaela Blyton shares the story of how she convinced some extremely picky koalas to try new foods in the midst of a conservation crisis. Spoiler alert: It involves starting a koala hotel, and inventing a pill with an unusual ingredient.

Coronavirus: Preguntas y Respuestas Para Niños

Si tienes preguntas sobre el coronavirus, tenemos las respuestas. El coronavirus nos está afectando a todos y puede parecer peligroso y difícil de entender. Por esta razón, Tumble reunió preguntas de sus oyentes y contactó con un experto para responderlas. Le preguntamos al Dr. Juan Dumois, un médico pediátrico de enfermedades infecciosas, lo que todos nos estamos preguntando, especialmente los niños:**** He escuchado que el coronavirus empezó con unos murciélagos y quería saber si esto es cierto. Y si fue así, ¿qué pasó?  ¿De dónde proviene el nombre del coronavirus? ¿Cómo se transmite el coronavirus de persona en persona? ¿Por qué el coronavirus parece ser más peligroso para la gente mayor que para los niños? ¿Puedo darle besos y abrazos a mi abuela? ¿Le puede dar coronavirus a mi mascota? ¿Cómo puede la ciencia ayudar a frenar este brote? Esta es una versión especial en español de Tumble, producida por Nuria Net y Alex García de La Coctelera Music. ¡Gracias a todos los que ayudaron con este episodio!
