This is Aerogel, which is "the lightest solid on earth"... about 99.8% air, with the rest glass. It looks like a handful of blue smoke. This is what the Stardust Capsule used to collect the samples of comet tail that it brought back to earth recently. (Article)You can't buy it on the open market of course... WRONG! You can get your own 2" x 2" block for $500 right here! Act now supplies are running out. (You don't get geek points for owning the small $25 dime-sized pieces sold here, but then geek points aren't everything.)
Other funkilicious high-res photos (like the one stolen above) to be found on the NASA JPL website, right here.
p.s. Makes a geekeriffic Christmas Gift for geeky bloggers everywhere, if you happen to know someone of that persuasion, Dad.

What would you do with it?
I would love it and hug it and hold it and kiss it and squeeze it and pet it and call it George.
Seriously, I would just put it on a shelf and show it off to people who appreciate stuff like that.
