Review on 🧊 20ml Silica Aerogel Sample - Tryuunion Frozen Smoke Aerogel Block, World's Lightest Solid for Science and Education by Stephen Parkell

I had concerns when I ordered this and those concerns were recognized. Not a product at all that does well with automated picking and ground shipping: instead of the pretty airgel cubes pictured on the order page, I got a small bottle of what's now called Aerosand. There are perhaps two pieces in the bottle worth exploring and one of them leaves a lot to be desired.
