Does anybody know some site or magazine that have some info about aerosolids ??(solids witha density of 98.8% of free space) nasa used it to take some dust from a comet recently thanks

You're talking about AEROGEL! easy google search once you have the name... but just in case,.......... http://stardust.jpl.nasa.gov/photo/aerogel.html

you can buy little chunks of the stuff on some sites, horribly expensive though.
i'd send you some but i'm fresh out, used my last stock making insulators for a plasma cannon array.

:susp: aerogel....... so thats why I can´t find anything ............. thank you a lot !!!!!!!!!!!!!!!!!

what will you do on an aerogel?
