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.

What would Earth be like if our oceans never existed? That’s what Charlie wants to know! We recruit Earth detective Lucia Perez-Diaz to help us track down clues hidden within our planet’s rocks. Our investigation takes us through the mysteries of how water got on Earth, the giant plates moving beneath our feet, and why our oceans are shaped the way they are. Lucia’s also an illustrator, and will draw us an Earth without oceans. What will it look like? Listen to find out.Learn more about how Lucia uses her detective skills to reveal the last 200 million years of Earth’s history, on our special bonus interview episode. It’s available to Patrons who pledge $1 a month or higher! You can support our show and get our ad-free feed on patreon.com/tumblepodcast.You can see some of Lucia’s illustrations on our blog at sciencepodcastforkids.com, along with other resources to learn more about water and plate tectonics on our planet!

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 patreon.com/tumblepodcast.
We’ll have free resources about bubbles on the blog on our website, sciencepodcastforkids.com.

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:
Ingredients
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)
Directions
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.
