World's Lightest Solid!

Aerogels are the world's lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels, though graphene aerogels are now technically the lightest.
At one point Dr. Steven Jones literally held the Guinness World Record for making the lightest aerogel and therefore lightest solid. If you're interested in learning more about aerogels, let me know in the comments as there is a potential trilogy in the works...
Huge thanks to Dr. Stephen Steiner and the crew at Aerogel Technologies. To find out more or buy your own aerogel sample, check out:
Thanks to Dr. Steven Jones and Dr. Mihail Petkov at NASA's Jet Propulsion Laboratory
And thanks to FLIR for loaning us the awesome high definition thermal camera. The footage is amazing!

  • I remember when I 1st watched a documentary when NASA used the aero gel on SOHO , I thought it was capturing the particles blasted off of the sun , but you said it was off a comet . Also , I remember watching another documentary on the man who " supposedly " was the 1st person to invent it , who was an Asian man . Wow , I was surprised to hear here that it was invented in the 30's . Nonetheless, my impression of the material stii is in complete amazement & awe . I knew when I 1st saw it , all the wonderful capabilities it can , & 1 day be used for ! Truely , 1 of the best inventions of my time if not the past millennium
