TUMBLE PRESENTS: Tai Asks Why Jul 08, 2022

Show notes

Since Lindsay and Marshall are on a break for the summer, we thought we'd share with you one of our favorite other podcasts! We present to you: Tai Asks Why.

Fifteen-year-old Tai Poole won’t rest until he’s uncovered the mysteries of the universe, one probing question at a time. In Season 4 of his Webby-winning podcast, Tai talks to everyone from NASA scientists to stand-up comedians to his equally curious little brother. If you’ve ever wondered what we can do when we’re anxious or if we’re alone in the universe, Tai has you covered. More episodes are available at hyperurl.co/taiaskswhy

What If Oceans Didn't Exist? Jun 10, 2022

Show notes

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 May 27, 2022

Show notes

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.

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.

The Seed Treasure Map [UPDATE!] May 13, 2022

Show notes

How many seeds sprouted in the historic Beal Seed experiment we covered in 2021? Find out in this updated version of one of our favorite episodes for spring! We tag along with scientists following a secret map on a mission under the cover of night, to find a buried treasure. It’s all part of one of the longest running, most legendary experiments in science history! We follow plant biologist David Lowry and his team on this secret scientist-spy-treasure hunt, which only happens once every 20 years. But things don’t go quite as planned. Find out what happens on this epic science quest.

To learn more about the Beal Seed Experiment, listen to our bonus interview episode with David. It’s available to Patrons who pledge just $1/ month or more on patreon.com/tumblepodcast.

Learn more about the experiment and plant biology on the blog on our website, sciencepodcastforkids.com.

Why Do Colors Exist? Apr 29, 2022

Show notes

Why do colors exist in the world? That’s what Phoebe wants to know. The answer might change how you think about the colors that you see! Neuroscientist and artist Bevil Conway bends our minds and our eyes, to show us how colors are the ultimate optical illusion. We’ll discover what color is made of, why even plants can “see” color, and what color can tell us about how our brains work. Take out your coloring supplies and prepare for a color journey.

Want to learn why we choose our favorite colors, or if the red I see is the same as the red you see? Listen to our bonus interview episode with Bevil, available on Patreon ad-free feed. Just pledge $1 a month or more to support the show, at patreon.com/tumblepodcast.

We’ll have free resources about the science of color on the blog on our website at sciencepodcastforkids.com.

What to Do About Trash? Apr 15, 2022

Show notes

Trash is one of the biggest problems on the planet. But scientists are coming up with solutions that might surprise you. In this Earth Day episode, we meet two researchers who are tackling trash in two very different ways. Kevin Solomon hopes to solve the challenge of recycling plastic with the help of meal worms, and Lily Pollans is figuring out what kids can do to help everyone make less trash. Find out how science can help tackle Earth’s biggest challenges - and how you can help.

Learn how one city learned to make less trash, in a special bonus interview episode with Lily Pollans. To listen, pledge to support us on Patreon for just $1 a month or more, at patreon.com/tumblepodcast.

We’ll have free resources to learn more about how to make less trash - and new solutions for recycling - on the blog on our website at sciencepodcastforkids.com.

Where did the asteroid that killed the dinosaurs come from? That’s what our listener Lucian wants to know. Prepare to hear a “podcast movie” about the fateful impact, starting with an explosive collision in space that sent asteroids careening towards Earth. Then we’ll discover the science behind the story, with the help of planetary scientist Sean Gulick. He led an expedition along with Dr. Joanna Morgan to drill into the impact crater - and find the final piece of evidence in the asteroid theory. This episode is sure to blow your mind.

Do Dreams Have Meaning? Mar 18, 2022

Show notes

Come on a trip to Dreamland, as we explore the history of dreaming - and how science changed their meaning, forever. Our guide is Sidarta Ribiero, neuroscientist and author of “The Oracle of Night.” We’ll travel back to ancient times when gods and goddesses appeared in dreams, visit the offices of Dr. Sigmund Freud, and watch as an 8 year old boy contributes to a huge scientific breakthrough - while he slept. Plus, we’ll send you off to sleep with the three steps to exploring the meaning of your dreams. Let’s get dreaming!

Want to learn more about dreams? Tune into our bonus interview episode with Sidarta to learn more about when dreams have meaning, and how dreams might make us better at learning.
