Tommy Technetium on Instagram: "Everything vibrates. Even liquid metal. You’re looking at droplets of a liquid metal alloy called Galinstan responding to sound waves. When the frequency is tuned just right, the droplets begin to oscillate in beautiful, star-like patterns — a striking example of vibration, resonance, and physics shaping matter. This isn’t CGI. It’s real science. To learn more about how sound can sculpt liquid metal, check out my latest YouTube video. I’ll link it in the comments.
