Moment Of Um

We’re back! We’ve officially moved into our new headquarters! Come unpack with us and get a tour while we fill you in on some big news. Plus, new episodes of Brains On coming later this month and new Smash Boom and Forever Ago after that. If you want to support the show or drop us a line, head to brainson.org. The best way to keep us going is to join Smarty Pass or donate here: https://brainson.supercast.com. Thank you! See Smash Boom Best LIVE in Princeton, NJ! Join us at the McCarter Theatre for a live, in-person version of Smash Boom Best, an award winning podcast for kids and families! Each live show takes two cool things, smashes them together and lets the audience decide which is best. Host Molly Bloom moderates a debate between two performers who make their case using facts fueled by jokes, physical comedy, and the occasional song and dance. At the end, the audience votes for the winner and crowns the Smash Boom Best – all while learning how to defend their own opinions and make the strongest arguments for their case. While we are in town, we are throwing a Smash Boom Spectacular Party right after the live show and YOU are invited! This won't be just any party. You will get to meet host Molly Bloom and our debaters. They'll be playing games with you, singing songs, answering your questions, and posing for photos. Plus, you'll get to take home an awesome, one-of-a kind Smash Boom Best goodie bag. You can gain access to this SBSP (Smash Boom Spectacular Party) by purchasing a VIP ticket* when you make your purchase. See you there!

They come in cool colors, catch popcorn kernels and sometimes even have spacers - it’s braces! Ever wondered how braces magically straighten teeth?

Send it to us at BrainsOn.org/contact, and we’ll help uncover the tooth. See omnystudio.com/listener for privacy information.

Waiting for a stoplight to turn green can be really annoying, especially when you’re running late. It would be awesome if you had a magic wand you could wave to get the light to change. But alas, such things don’t exist. But how do stoplights know when to switch colors? We asked Jerry Kotzenmacher with the Minnesota Department of Transportation to help us find the answer. Got a nagging question that just won’t yield? Send it to us at BrainsOn.org/contact, and we’ll put you in the express lane to answersville. See omnystudio.com/listener for privacy information.

Happy Snake Week! Every episode this week explores a different question about our slithery friends. Did you know that, out of the roughly 3,000 total species of snakes, only about 10-15% are venomous? But how do those snakes make venom in their bodies? We asked snake scientist Emily Taylor to help us find the answer. Got a question that’s biting at you? Send it to us at BrainsOn.org/contact, and we’ll search for the answer-dote!

Happy Snake Week! Every episode this week explores a different question about our slithery friends. Zoos have to have all kinds of foods available to feed the different species that they care for. Animals like elephants, zebras and buffalo eat plants. Predators like lions, foxes and bears have a much meatier diet. But what’s on the menu at the snake house? Snake cake? Snake steak? Snake grapes? We asked biologist Emily Taylor to help us find the answer. Got a question snaking throughyour brain? Send it to us at BrainsOn.org/contact, and we’ll help squeeze out an answer.

Some people have allergic reactions to foods like peanuts, sesame, and raw eggs. But when people with egg allergies eat cooked eggs, there’s no reaction. What’s up with that? We asked pediatrician Liz Placzek to help us find the answer. Have you hatched a really great question? Send it to us at BrainsOn.org/contact, and we’ll help find EGG-xactly what you need.

When you’re sick, it’s important to get plenty of rest to help your body heal. But it can be hard to sleep when your brain keeps showing you bizarre fever dreams (Like being chased by a giant fireball! Or swimming in nacho cheese!) Why do we have strange dreams when we’re sick, anyway? We asked dream researcher Michael Schredl to help us find the answer. Got any burning questions? Send it to us at BrainsOn.org/contact, and we’ll search feverishly for the right answer! See omnystudio.com/listener for privacy information.

Dogs come in so many different sizes, from the tiniest teacup terrier to the giant Great Dane. How did we get such a delightful assortment of these furry best buddies? We asked Brains On producer and archaeologist Anna Goldfield to help us find the answer. Got a question that’s been hounding you? Send it to us at BrainsOn.org/contact, and we’ll make sure to bark up the right tree! See omnystudio.com/listener for privacy information.

We chew our food, swallow it, and our stomach goes to work on digesting! Our bodies absorb the nutrients they need and then we poop out the rest. Here on Earth, the whole process takes somewhere between one to three days. But what about in space? Do astronauts digest food as quickly as they do on Earth? We reached out to space scientist and science communicator Maggie Aderin-Pocock to get the answer! Got a question you’re chewing on? Send it to us at BrainsOn.org/contact, and we'll spit out the answer. See omnystudio.com/listener for privacy information.

Did you know the tallest building in the world is a skyscraper in Dubai called the Burj Khalifa? It has 163 floors and weighs as much as 100,000 elephants! But how can the Earth even support such a huge building?! Why doesn’t the ground just collapse underneath it? We asked geologist Rónadh Cox to help us find the answer. Got a question that’s weighing heavily on your mind? Send it to us at BrainsOn.org/contact and we’ll help build you up with a great answer! See omnystudio.com/listener for privacy information.

You fart. I fart. Your dog farts. We all fart! Or do we…? Birds don’t fart, and they’re the closest living descendants of the dinosaurs. So, did dinosaurs fart? We asked paleontologist Kallie Moore to help us find the answer. Got a question rumbling around in your brain? Send it to us at BrainsOn.org/contact, and we'll find you an answer TOOT-suite!

Happy Dinosaur Week! Every episode this week explores the ancient marvels that walked the Earth millions of years ago. Fossilized bones and footprints help scientists figure out what these prehistoric creatures looked like – but how do we know what they sounded like? We asked paleontologist and science journalist Shaena Montanari to help us find the answer. Got a question that makes you want to roar in frustration? Send it to us at BrainsOn.org/contact and we’ll find a dino-mite answer. See omnystudio.com/listener for privacy information.
