Today's story is a mystery, shockingly hot, and vanishingly tiny. It starts with a sound, rising like a mist from the marsh, around a dock in South Carolina. But where it goes next - from submarines to superheroes (and yes, Keanu Reeves!); from the surface of the sun to the middle of the brain - is far from expected. Producer Molly Webster brings her family along for the ride. Enjoy the adventure, before it...implodes.  Produced by Molly Webster and Annie McEwen. Reported by Molly Webster. Guest sound designer, Jeremy Bloom. Special thanks to Kullervo Hynynen, James Bird, and Lawrence Crum.  After you listen to the episode (spoiler alerts): Wanna see the shrimp bubble in super slowmo?

Now, they are anything but.  Today we explore the story of one man, who - in an instant, changed the art of bubble blowing and what it means to be a bubble forever.  Produced by Simon Adler Special thanks to Megan Colby Parker, Gary Pearlman, David Erk, Rick Findley and everyone who came out to blow giant bubbles with us in Brooklyn's Prospect Park.  You can hear Jad's bubble dance party song here
