Its not often we get to see sound.

One classic physics experiment, however, allows us to do just that.

Aviral post on Redditdemonstrates what this looks like in practice using a Rubens Tube powered by a trumpet.

The mesmerizing result is a spectacular display of scientific principles.

The physics experiment was created by German physicist Heinrich Rubens in 1905.

The pipe is then lit and a standing flame appears.

A classic physics experiment called Rubens Tube allows us to see sound.

This viral trumpet performance demonstrates its principles.

The physics experiment was created by German physicist Heinrich Rubens in 1905.

Here’s an explanation of how it works and the setup.

This concept has been used in other musical parameters.

The oscillating pressure of the sound waves lets gas escape and shapes the sound curve.

It can look quite different depending on the sound being made at any given time.
