Shattering glass with the World’s Largest Horn

How do horns amplify sound? Why are they flared at the ends? And how do airhorns work? Mark Rober wanted to find out so he spent eight months building a massive air horn... perhaps the world's largest horn. In this...

A colorful Chladni pattern demonstration

Watch as Chladni patterns form on a metal plate, a teaching demonstration "spiced up" with colored sand by associate professor of physics at UNC Charlotte skullsinthestars. The video is accompanied by Prelude from Sui...

The Coupled Pendulum, a physics demonstration

See the simple laws of physics at work: Two pendulums swing on a string, transferring energy from one to the other and back again. This demonstration by MarkHacks, made with cardboard, screw hooks, tape, string, and t...

“Balloons look really weird when they resonate.” – Steve Mould

What is the resonant frequency of a balloon? Steve Mould hooked up a balloon to a scientific vibration generator to find out. Resonating balloons look really odd on camera. What you see is a sort of slow motion. ...

The Inverted Glass Harp

We love glass harps – instruments made from wine glasses that are filled with different amounts of water to create a series of desired pitches. In The Inverted Glass Harp, Dan Quinn shows us that empty glasses can als...

Resonance, forced vibration, and a tuning forks demo

A U-shaped fork of steel first invented in 1711 by trumpet player John Shore, the tuning fork is a tool produces a specific note that helps musicians keep their instruments in tune. They also are a great conversation ...

Breaking a glass with sound

From Dara Ó Briain’s Science Club, watch as Professor Mark Miodownik finds the resonant frequency of a wine glass, as indicated by the small vibrating slip of paper balancing on the edge. When he cranks up the volume,...

CYMATICS: Science + music = audio frequency visualizations

With help from a Chladni Plate, vibrating liquid on a speaker dish, a hose pipe optical trick, ferrofluid, a Ruben's Tube, and a Telsa Coil, New Zealand musician Nigel Stanford showcases audio frequency visualizations...

Mercury Hz: Sound waves passing around & through mercury

From “science on a budget” YouTuber Nick Moore, watch this drop of mercury being vibrated from ~120Hz down to ~10hz. We've seen resonance demonstrated before in Chladni Pattern v...

Making sounds visible: Sound vibrations transform colorful sand patterns

Japanese performance artist Kenichi Kanazawa taps a rubber mallet on a steel table to make sound vibrations that create beautiful transforming sand patterns. Using a scientific sound-visualizing process called Cymatic...

Chladni Plate: Sand Vibration Patterns

Rest your hands on a speaker playing loud music. Feel the sound vibrations? Now, you might want to adjust your volume for this one. Sound frequencies produce a variety of increasingly intricate resonance patterns. An...
