Frozen Smoke – Solid Air – Aerogel Brick

Aerogel Brick - Frozen Smoke - Solid AirThis picture is of a 2.5kg brick supported by a piece of aerogel, the worlds lightest solid material. This particular piece weighs in with a mass of 2 grams.

Aerogel is nicknamed ‘frozen smoke’ or ‘solid air’, due to the fact that it is composed of 99.98% air by volume. Aerogels are a diverse class of amazing materials with properties unlike anything else known. They exhibit the lowest thermal conductivity of any known solid, and are the lowest density structural materials ever developed.
