Now in the Boing Boing Bazaar: chunks of aerogel! $50 buys you a pair of aerogel discs.
Silica aerogel, the infamous and ethereal material comprised of up to 99.98% air, can be yours at last. Known for its superinsulating abilities, ultralow density, and its use on the Mars rovers, silica aerogel is just one member of the amazing class of materials known as aerogels, which promise to revolutionize everything from buildings to electric energy storage to hydrogen to lightweight structures.
These discs here are the old-fashioned "Classic Silica" flavor of aerogel and are composed of 96% air. While in principle capable of supporting 2000 times their weight in applied force, remember that 2000 times almost nothing is a small number, and that in its classic form, silica aerogel is fragile.
This form factor of aerogel, what we call "monolithic" aerogel, is best for curiosity, display, shooting lasers through, etc.
