Aerogel is (I think) almost as light as air. I'm wondering if it's possible to create an aerogel-like substance that has no air molecules spaced in between its atoms. And if that's possible, would it be lighter than air?
If that were the case, it would have to be disposed of carefully. If you dropped it outside, it would just float up to, say, 10,000 feet altitude and stay there. Or until it "washed ashore" on a mountain. Or got hit by a plane.
Then there'd be a new job: LtA (Lighter than Air) Aerogel Waste Disposal. You'd fly around in a Zeppelin armed with a big net, as you went about rounding up floating clumps of LtA aerogel before they got hit by some plane....
I have no idea what any of this means, but I have held aerogel in my tiny fist, and it is supercool
The lowest density solid, 7x10 2
• The smallest pore size, ~ 50 nm
• The highest porosity, >99.9 %
• The lowest thermal conductivity, 1100 m 2 /g
• Low tensile strength, 1 x 10 13 m 2
I am an aerogel BNF.

Sometime back I posted a link to where you could buy the stuff. I think it was about $70 for a small piece.
Please don't sigh
Okay, that's unreasonable, dictator ita.

Must be less than 30 RPM.
flea, did you see when I mentioned the other day that I went past Chicago Gyros (which hasn't been BRIGHT BLUE for a very long time, damn it), and it's been all renovated and yuppified inside, so that the inside looks like a Panera Bread or some such?
It's very traumatic. Chicago Gyros is *supposed* to be skeevy, damn it.
There's a headline reading "Midwest gets pounded with a foot of snow". I'm imagining something like the Monty Python opening credits.
