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/

  • 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.
  • 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!
  • That aerogel is like a constant ‘Oddly Satisfying’ moment
  • 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.

    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
  • Aerogel: iam 99.8% air but why do i hear boss music playing Lays: are you challenging me?
  • @1Chitus
    Wow, crazy how something so simple can make such a big impact. I’m sure there’s so much more we can do with this in do time. Very interesting👍🏽

    Aerogel - I’m the closest to air possible Lays - Observe

    love how chocolate takes mad long to melt under a fire but melts in 5 seconds in my hand
  • @savv.123
    This was so well explained! ✔️❤️
  • Thank you so much for uploading this video. It is helping me get through the pandemic!
  • @zuko1569
    It looks like an ice cube but it somehow died and turned into a ghost
  • It's one of best video I have seen since last 21 years 🙂
  • Would aerogel make for good screen protectors for phones since it scatters the color blue more then red/yellow?
