Tinkercast | Wondery

Wow in the World is the #1 science podcast for kids and families, sharing the most amazing stories in science, technology, and new discoveries happening in the world around us. 

Each week, join hosts Mindy Thomas and Guy Raz as they take curious kids and their grown-ups on a cartoon for the ear journey filled with laughter, adventure, and wow-worthy stories. From the tiniest microbes to the farthest reaches of space, every episode of Wow in the World inspires wonder, fuels imagination, and makes science fun for the whole family. 

New episodes of Wow in the World come out every Monday for free! Plus, each week listeners get even more opportunities to say WOW with two other shows: Two Whats?!

Wow in the World

Can laughter really turn a bad day around—and boost your brainpower? When Guy’s feeling grumpy, Mindy takes him for a walk in the park to cheer him up. But what they find there is no ordinary stroll: a crowd of gigglers… and a very special stand-up act led by none other than Sesame Street’s Elmo! As the jokes fly and the laughs roll, Mindy reveals the latest science behind why laughter is seriously and scientifically good for you—from your brain to your belly! Will Elmo’s comedy magic turn Guy’s frown upside down? It’s the WHO, WHAT, WHEN, WHERE, HOW, and WOW in the World of scientific benefits of LAUGHTER!
