Aerogel apparently holds 5 record properties, including the best insulator and lightest solid on the planet. It is used by NASA to collect space dust, and this in turn was an inspiration for Liliane Lijn to produce a piece of work using Aerogel at Riflemakers in Soho (London) – see here.

We have a piece of Aerogel, kindly provided by Airglass AB, and it is extraordinary stuff, and visually absolutely beautiful. Half way between glass and nothing, like a chimera or ghost.

It does weird things with light; it looks yellow outdoors and blue indoors; light reflects/refracts off it in interesting ways.
