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: www.aerogeltechnologies.com/

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! www.flir.com/

    Aerogel: iam 99.8% air but why do i hear boss music playing Lays: are you challenging me?

    It's great to know about aerogels that have really great and interesting properties. Watching the video about the various uses and roles of the aerogel, I found it very attractive. I'm also looking forward to watching the aerogel develop further. Not only do we hope for more innovation and development in the future, but we also look forward to seeing aerogels being used in new areas.
  • As a thermal engineer, I appreciate this great scientific innovation. Looking forward to sharing this great video with my thermal group at Villanova University, USA!

    So you are basically holding a piece of the sky

    I remember reading about this in USA Today about 30 years ago. They had a picture of an Aerogel cube in a person's hand, and a candle flame in the background. They said that Aerogel worked so well, that if a room was fully insulated with the substance, the candle flame would be enough to heat the room. I thought that was so intriguing. And yet, I never really heard much about it again. I'm guessing it's both very expensive and very fragile to be practical in mass insulation production.

    Found this by accident & am so glad I did!! Fascinating!
  • @leika8838
    "99.8% Air" So the company producing this is associated with Lays, huh?
  • Thank you so much for uploading this video. It is helping me get through the pandemic!

    love how chocolate takes mad long to melt under a fire but melts in 5 seconds in my hand
  • @YoAndyZou
    The fact that they did this in 1931 is actually what blows my mind; it reframes what I think of scientific progress and capability back then
  • @savv.123
    This was so well explained! ✔️❤️

    Aerogel: 99.8% air Plankton: 1% evil, 99% hot gas

    “This object is 99.8% air” Lays: finally, a worthy opponent, our battle will be legendary
  • @arnabrooj5298
    It's one of best video I have seen since last 21 years 🙂
  • Clicked on this video by accident and now I love it and won’t stop watching it
