The world’s lightest known solid, Aerogel, weighs only three times as much as air. As air, mind you. You could practically breathe the stuff, but you wouldn’t want to because, basically it’s glass. Really, really, fluffy glass.
It has been used by NASA as insulation for the Mars Pathfinder Rover. Not only is it a great insulator, but it is also made from silicon dioxide, so it can do other glass-like activities. NASA recently used it in the Stardust mission as a collector plate for comet & interstellar dust samples.
The stuff is also incredibly expensive, but that didn’t stop Jason Wells from putting it through the paces. He fried it, shocked it, froze it, baked it, soaked it and eventually smashed it. It’s all highly documented, with pictures, and makes for some good lunchtime reading. Especially since you’re never going to go out and actually buy the stuff.
Wtf? I see no story.
hahahahaha solid air
3X air? isn’t air weigh nothing almost?
Of course air has weight. All matter has weight. Just cause you cant see that on a bathroom scale, doenst mean the weight isnt there. Lol
You can actually buy this stuff at unitednuclear.com
like i know how much air freakin weighs
1m cubic of air weights 1kg, so 1m cubic of this stuff would weight 3kg, thats very light, compared to water, 1m cubic of water weights 1 ton
that is some f-ed up glass
3x Air? Thats like saying 7x Happiness
