One thought on “What Does the Lowest-Density Substance on Earth SOUND Like?

  • Air is a substance (comprised of a mixture of many substances). Aerogel sinks in air. Air is on earth. Aerogel therefore is not the lowest density substance on earth. The sound in the video is not that of aerogel, but that of its impact with a wood (Scandinavian quasi-wood, Ikea?) surface. So basically, this article is WITHOUT substance.
