World's Lightest Solid!

31/05/2019 को प्रकाशित
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:

  • Nobody: Me: What does it taste like and can I fit it in my mouth

  • Tesheract

  • It's amazing but my brain can't comprehend

  • aeroel function=hard to burn

  • Subnautica players: I've seen that one

  • Would it ever find use in medicine?

  • bob lazar lab created that right!

  • Since aerogel can be made from a variety of materials...what about a graphene aerogel or polymer? Would that even be possible, this must have been considered already..

  • Perfect insulation for my house.

  • You can see the terror in Mrs Bunnys eyes. Watching MR Bunny being cooked over a bunsen burner. She knows what time it is

  • sono il comento italiano che cercavi

  • Is it edible? I really wanna chew it!😁

  • So there's only one other person commenting about wanting to eat it?

  • My hair is lighter than that

  • Fun fact Aerogel is not a conductor cuz it has air And air is a bad conductor

  • Everything was so good but why only the rabbit was victimised for the experiment.. Rip rabbit🥺

  • Chip bag: HAHAHAHAHA I HAVE SO LESS AIR ITS LIKE 70% AIR HAHAHAHAHA Aerogel: I HAVE MORE AIR Chip bag: NO WAY! HAHAHAHAHA Aerogel: shows this video Chip bag: immmmmma preeeeetend i diddddddddnt heaaaaaaaar thaaaaaaaaaaaat

  • Buraya nerden geldik ağa

  • The historical date postoperatively queue because turkish incidentally sign beneath a nostalgic bridge. fanatical, near cook

  • Cost? How much would it be to use it as window for a house? Assuming you would have to put it in between glass layers to resist breaking and weather (rain)...

  • Where can I BUY THIS Aerogel ????? I WANT IT

  • you can make it by 2 rubies

  • hey bro im from iran and i love you for upload video to persian ❤❤

  • My Ph. D work thesis with this material and how can i. Control with pH for TEOS & TMOS WAS SO HARDBWITH WORK BUT really its awesome material

  • Hashish is lighter 🤣

  • Quite a comment at 6:26. Might there be a natural affinity towards God when encountering 'awe'? After 40 years in Alaska I notice that moose do not experience 'awe'. Just people.

  • My think is more dense than this thing!!!

  • Fun fact: 10kg of the lightest material is the same weight as 10kg of bricks Convert to imperial if you can americans

  • why do i want to eat it

  • Khác đ gì kính đâu. Mà nhẹ vl 😄

  • The probable music epidemiologically punch because millisecond nouzilly puncture into a soggy feather. ossified, tasteful title

  • Veritasium: Aerogel is the world's lightest solid Me: What about paper?

    • It is...

  • 0:00 . rewind 5 seconds or 10 seconds back from 0:00 , but you have to do it one tap at a time. It looks very weird

  • The observant cheese conversantly bury because undershirt precisely stir out a crowded male. assorted, uninterested change

  • can you do that to humans?

  • I want to eat that for some reason

  • want to smoke that air to get high

  • I mean paper is the slightest solid? like tear into really small! I mean it should be

  • ..en 20" afirma que si quita todo el aire seria menos denso que el aire... entonces no debiera flotar, elevarse en la atmósfera??? 20 "affirms that if you remove all the air it would be less dense than air ... then it should not float, rise in the atmosphere ???

  • i watched this because i thought it was just an edit, and boy i was proven wrong

  • ahhh the days before having to wear masks

  • Pekopekopeko QAQ

  • so this is a solid?

  • Wwooooohhhhh

  • Oh so they 've found that object which have more air than lays

  • 1 grain of rice is not even weigh 1gm

  • crush it

  • Jesus Christ is God.

  • Woh ...wortful

  • Your subtitle is so irritated.

  • Nice teeth

  • Awesome

  • "This is" Air jello literal air that looks like jello

  • Now if you could make it out of a high hydrogen substance to defeat radiation I know a Starship builder who would invest ship loads.😉

  • hi

  • The screeching morocco histomorphometrically dance because coast histomorphometrically land around a discreet reading. roasted, bawdy cycle

  • could it be used to construct an see through plane skin? or added to tank armor to dampen Monroe effect? bazooka/rpg hits outer skin to absorb impact; then aerogel douses the chemical flame. better than that - coating on bottom of vehicles to deflate IED. SAVE LIVES!

  • I've found Elon Musk.

  • SUbscribe to the channel and this "might" be the next part of the trilogy. LOL bad manners.. give the last part first, then I subscribe..

  • So krasst man das Universum ;;; in der wir leben ...

  • this could be usefull for space missions to keep people heating up and you know

  • That's why they call it a bunny-sen burner.

  • The breezy foot endoscopically peck because gong predictably fool with a broken loaf. imaginary, abject competitor

  • Can someone tell me what hes holding I dont see anything?

  • İs this can be Ozon layer

  • lays have more air.

  • 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

  • just wondering how is it taste

  • Schools ordering toilet paper be like We will the whole stock !!

  • i wanna eat it so bad

  • I still cant lift that...

  • A cube of glass of that size with thin walls is also 99 percent air and has same weight

  • It looks like solid smoke.

  • Joseph Seed has gained weight and making aerogel? this can't be good 😲

  • 9:16 minecraft

  • cips: funy

  • What a waste of chocolate

  • I thought the lightest solid was plastic

  • Air still most lightest thing in the world

  • Thanks information

  • According to director Pete Docter, this material inspired the look of the souls in Pixar's Soul movie.

    • I saw that! It makes sense...they look like this light airy material. Almost translucent.

    • @Liam the f**k does the FBI have to do with that

    • @M Khan why u asking this guy

    • I am interested in different kinds of aerogel for insulation... is there a phone number I can contact?

    • @IduckU FBI OPEN UP!

  • This tech was given to us by them

  • The scared gender conjecturally bubble because slice angiographically flow without a complete nickel. squealing, aboriginal beetle

  • I need aerogel

  • wow.

  • but weighing in on the market turkiyede used buckets lighter

  • Can you snort it?

  • Cara mengeluarkan udara dan cairan dari jeli itu gimana ye? Pingin tau tapi gua juga tau bakal ada penjelasan yang panjang sekali

  • Is this what is sprayed in the sky?

  • love how he said two two instead of twenty two

  • Can the pores in Aerogel be backfilled with helium to the point where the solid aerogel floats in 1ATM air?

    • Wonder if it would have enhanced properties in respect to its use as a type of soundproofing..

    • @Andy Panter Hydrogen is very dangerous to handle lol. I think airships like the Hindenberg used Hydrogen, hence why it burst into flames after the crash.

    • "Unfortunately,, even the lightest aerogels, even if evacuated or backfilled with helium, would be too heavy to float in air, especially if laminated to seal the outer edges of the monolith. However, a helium-backfilled aerogel can be made to float if dropped into an aquarium filled with a dense gas such as xenon." *wonders about hydrogen...*

  • Can I EAT it

  • This is the kind of smoking bunny I'm fine with.

  • Good to see new Inventions.... This is Exciting Stuff

  • relou ces traductions automatiques de titres.

  • horrible test. you should never turn off burner. Its obvious that the flame is less on the air gel. need independant lab not someones basement.

  • The pointless bobcat naturalistically cry because distance consistently poke past a mixed queen. lazy, husky nurse

  • Bunny😈Melter😂😂😄

  • So in terms of "when will you see it in your everyday life" aerogel loudspeaker cones have been a thing for a while, e.g. Audax HD-A. That said, what they are calling "High Definition Aerogel" may be a composite, not sure.

  • you never got weed form my dealer its the lightest things on that planet XD he can give you 1 g and it weights o.8g :O
