Its really interesting to take a fact (like this gel is a nano-structure of silicone that is spongelike and contains over 99% air) and actually see it and see how it works...check it out. I'll post the photo of the stuff in the album, too. http://www.nasa.gov/mission_pages/stardust/mission/aerogel-index.html Fri, 20 Jan 2006 11:44:12 GMT http://CRNano.tribe.net/thread/7d5292db-8609-424d-ba29-97d56a8b7632#5531189c-f490-459e-9067-b0cf32efda6b Michael David 2006-01-20T11:44:12Z
