Veritasium: World's Lightest Solid!

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: http://www.aerogeltechnologies.com/

And thanks to FLIR for loaning us the awesome high definition thermal camera. The footage is amazing! https://www.flir.com

    This is incredible and could be the start of smarter more ecological, a revolution for insulation in the world for homes and other things.

    Wait a minute. So you compare 1 mm glass to 1 cm aerogel? and aerogel was only two-four times beter? i.e. with the same thickness aerogel is much worse?
    And instead of using something small you use a huge bunny so hot air gives you an excuse for it melting? wtf?

    I never found the fluid to be super-critical. It offers constructive criticism but people take the fluid's snarky delivery as it being judgmental.
