Best Viewed with IE or Opera. Sorry, Firefox works, but loses some sidebar layout,
'my profile' and other stuff... Anybody with a fix, please leave a comment. Many thanks in advance.
That said, if you must use Firefox (and I don't blame you, it's become my browser of choice, too)
...get the "IE Tab" extension. This allows you to view problem pages with the IE rendering engine. Very cool!
United Nuclear - Aerogel - STRANGE STUFF
Aerogel is made from Silicon Dioxide, the same material as ordinary Glass,
only 1,000 times less dense.
Aerogel (also called 'frozen smoke' because of its hazy blue appearance), is a truly remarkable material.
It is the lightest and lowest-density solid known to exist, and holds an unbelievable 15 entries in the Guinness Book of World Records, including best insulator and lowest density solid.
Aerogel is composed of 99.8% air and is chemically similar to ordinary glass.
Being the world's lightest known solid, it weighs only three times that of air.
