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!DETAILS & TICKETSMcCarter Theatre CenterOctober 26, 2025 at 3:00pm ET91 University PlacePrinceton, NJ 08540Buy Tickets HereSee omnystudio.com/listener for privacy information.

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?

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?

The sounds of the ocean are so relaxing… the waves crashing on the sand, the gentle roar of the surf.

All living things on Earth are related. To help keep track of how close those relationships are, scientists organize life on Earth into groups using a system called taxonomy. Sometimes, taxonomy can be surprising – like, did you know that humans are more closely related to mushrooms and other fungi than we are to plants? How does that work? We asked microbiologist Christine Salomon to help us find the answer.Got a question that’s in a class by itself?
