Could Sound Make You Levitate?
The Rest Is Science
Intro
Hannah and Michael open with sponsors and introduce the episode's theme of acoustic levitation and curiosities.
Imagine: a series of objects floating in midair without magnets, strings or visible supports. With acoustic levitation sound waves alone can suspend droplets, beads and even small solids to seemingly defy gravity!
In this episode of Field Notes, Hannah shows Michael this astonishing device, revealing how precisely tuned sound can manipulate matter. Behind the mesmerising floating objects lies a combination of physics, mathematics, and engineering that turns vibrations into invisible hands.
How do sound waves create stable points in space? What can acoustic levitation teach us about controlling particles, studying delicate chemical reactions, or even exploring new materials? And why does watching something float so effortlessly feel like glimpsing...a little magic?
Welcome to The Rest Is Science: Field Notes.
Every Thursday, Hannah and Michael rummage through their personal troves of scientific treasure and source discoveries that explain our understanding the universe, oddities that scramble our brains, objects that hint at forces we’ll never see...and a few things that are essentially just plain cool.
Expect deep dives into the science behind each pick, the spark that grabbed their attentions, and the sheer delight they get from sharing it all with you.
They’ll also be tackling your questions, so email The Rest Is Science at therestisscience@goalhanger.com.
