In the video above, watch as YouTuber brusspup sprinkles sand onto a metal plate attached to a speaker, and then turns up the volume to bring the whole thing to life in a pulsating, dance of intricate patterns.
Needless to say, it’s beautiful and mesmerising all at the same time.
But the science behind the video is just as cool - this experiment is known as the Chladni plate experiment. As brusspup explains over on YouTube, it required a tone generator, a speaker and an attached metal plate.
When you play a tone through the speaker, specific frequencies cause the plate to vibrate in particular patterns - and some regions will vibrate in opposite directions, causing regions of no vibration called nodal lines. And when you add sand, the grains all "fall" into those areas, creating art-like geometric patterns.
As you can see, the location of these vibration-free regions change as the frequency varies resulting in a pulsating, resonance dance. In the above video, brusspup has tested the patterns of different tones, and set the whole thing to music.
