Frozen Smoke / Aerogel

Aerogel is a manufactured material with the lowest density of any known solid.

It is derived from a gel in which the liquid component of the gel has been replaced with a gas. The result is an extremely low-density solid with several remarkable properties, most notably its effectiveness as a thermal insulator and its extremely low density.

It is nicknamed frozen smoke,solid smoke or blue smoke due to its translucent nature and the way light scatters in the material; however, it feels like expanded polystyrene (styrofoam) to the touch.
