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.

How does an owl’s tail help it fly? To better see the role of the tail in raptor aerodynamics, researchers at the UK’s Royal Veterinary College recorded birds of prey flying through clouds of tiny helium bubbles. According to the science journal Nature, analyzing the swirling motion of the bubbles enabled the scientists to discover […]
Thirty years ago today, the Voyager 1 spaceprobe had completed its ncounters with the outer planets and was careening out of our solar system. The time came to shut off the probes’ cameras to preserve power and memory for the other onboard scientific instruments. But before engineers flipped the switch, one last photo opportunity was […]
While scientists have studied Moon rocks for 50 years, researchers have for the first time conducted deep analysis on a single grain of lunar dust, atom by atom. Using a common materials science technique called atom probe tomography that’s not widely used by geologists, the Chicago Field Museum’s Jennika Greer and colleagues probed the grain […]
Despite legalization in 11 states and decriminalization in 15 more, marijuana-based products are still an often tough sell with many Americans. While the psychoactive THC portion of the plant remains controversial, the medicinal impact of the non-altering component of cannibis, CBD, is widely hailed. Many portions of those claims still await medical verification, but for […]
If you remember your Norse mythology (or just watched Marvel’s Thor movies), you’re probably familiar with Heimdal, the god whose ever-watchful eye was entrusted with protecting the home of the gods in Asgard. Back on Earth, Heimdal Thor is also the name of a security package from Heimdal Security, that’s actually dedicated to much the […]
Everyone’s got their nose in a phone these days, and that doesn’t seem like it’s going to change anytime soon. With the increase in mobile device and e-commerce reliance comes increased need for developers who can build the apps we’re all so glued to. In fact, employment of devs is expected to grow up to […]
