  • 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/

    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.

    What if they made a whole house out of it? Would I be able to pick up a house?

    Okay so if you could remove the air in the aerogel to make it lighter and you didn’t then it clearly isn’t the lightest solid
