Man Uses Violin Bow And Sand To Create Incredible Geometric Shapes Using Soundā€”And It’s Science FTW šŸ˜®

A video of a man using sound to create geometric shapes out of couscous has gone viral on Twitterā€”and it’s easy to see why.

The original video was published on YouTube in 2016 by Steve Mould, “a science presenter on TV and on stage,” who participatesĀ in the science-comedy show Festival Of The Spoken Nerd.

In the video, which has received over 1 million views, Mould uses a large sheet of metal, a violin bow and couscous (uncooked, as he points out) to demonstrate two-dimensional standing waves in the form of “Chladni figures.”

As Mould explains, the amazing geometric shapes are named after Ernst Chladni, the German physicist who invented thisĀ technique to display them around 1787ā€”although he used sand instead of couscous.

MouldĀ then goes on to explain how the actual math that explains the phenomenon was largely discovered by mathematicianĀ Sophie Germain, who received very little recognition for her work during her lifetime.

Prepare to be dazzled:

On Tuesday, an edited version of the video was posted on Twitter, by experimental social psychologist Simone Schnall, where it has since racked up over 2 million views, 57,000 retweets and 160,000 likes.

Commenters on Twitter were impressedĀ with the effect:

And thankful to Schnall for posting it:
