Don’t ask me how I came across this link – extreme boredom maybe?? Regardless, even my inner geekiness had never seen some of this stuff so I thought I would share.

Warning – I’m guessing the site “Cracked.com” is run by 20-something boys who still think swearing for swearing sake is funny. (Ok – some of it is!). But if you can get passed that, it is some pretty interesting stuff. If you don’t want to, google the following and see what you get:

stardust-aerogel

2. Aerogel: a manufactured material with the lowest density of any known solid.  Check out this video at You Tube: http://www.youtube.com/watch?v=kHnen2nSmDY

The article has other things like transparent aluminum and carbon nanotubes, but I thought the above were the coolest.
