Bringing life to 18th-century physicist Ernst Chladni’s famous Plate Experiment, YouTuber Brusspup demonstrates incredible geometric patterns that form when sand is placed on a metal plate attached to a “tone generator.” This art-meets-science video really resonates with us.

Here’s how it works: As the frequencies coming through the speakers increase, so do the plate’s vibrations. The sand gravitates towards the least-vibrating areas, causing the patterns to become increasingly complex as the pitch goes up. THE UNIVERSE.
