Aerogel is created by evaporating the liquid out of gel, leaving behind just the structural framework — making it 99% air with extremely low density. Despite being mostly nothing, it has exceptionally low sound conductivity, making it an ideal acoustic insulator. Researchers in Singapore have now made flexible aerogel sheets usable in real-world products like shoe soles.
