It's time for the....Mystery Sound Extravaganza!

March 10, 2026·34 min·1 clip

Molly Bloom and kid co-host Juniper from Philadelphia play a Mystery Sound Extravaganza on Brains On, working through eleven listener-submitted mystery sounds — from a snow shovel cracking ice to butter bubbling in a skillet, a blood pressure cuff inflating, dry ice being scooped, and a dad patting a baby's mouth. Juniper goes on an impressive guessing streak, correctly identifying the snow shovel and dry ice. The episode also features drawings from the mailbag, a plug for the Brains On Universe Smarty Pass, and upcoming live show dates.

As heard by us

A light, guessing-first episode that keeps curiosity moving.

The episode turns a simple mystery into a quick run of curiosity: sound first, explanation after. It moves from live-show news into the guessing game without much delay, and Bob's CFO bit gives it a playful side path without breaking the thread.
