This video by YouTube user and musician Brasspup shows us one of life's little moments where science and art can become one and the same.

The Chladni experiment itself is nothing new. It's a technique that shows how sound waves affect physical matter and the air around us.

It also has an extremely cool side effect which is that if you place small granules like salt or sugar on a base plate attached to a speaker then once a sound is played the granules create a stunning array of patterns.

The patterns are actually showing the nodal lines, areas on the plate where the metal isn't resonating allowing the granules to sit still.

The technique is still used in the construction of musical instruments however it serves the double purpose of entertaining people like us.
