It’s basically just a gel made from silicon, except all the liquid has been taken out and replaced with gas instead. If you hold a small piece in your hand, it’s practically impossible to either see or feel, but if you poke it, it’s like styrofoam.</p> <p>Aerogel isn’t just neat, it’s useful. It supports up to 4,000 times its own weight and can apparently withstand a direct blast from two pounds of dynamite. It’s also the best insulator in existence, which is why we don’t have Aerogel jackets: it works so well that people were complaining about overheating on Mt. Everest.”</p> </blockquote>http://rocksrock.tumblr.com/post/5903375371http://rocksrock.tumblr.com/post/5903375371Fri, 27 May 2011 14:47:43 -0400<img src="http://25.media.tumblr.com/tumblr_ll1d4vf2Vo1qaj6xyo1_500.jpg"/><br/><br/>http://rocksrock.tumblr.com/post/5887455553http://rocksrock.tumblr.com/post/5887455553Thu, 26 May 2011 23:22:48 -0400<img src="http://25.media.tumblr.com/tumblr_llsc50Y8PM1qzi6nqo1_500.jpg"/><br/><br/>http://rocksrock.tumblr.com/post/5864951375http://rocksrock.tumblr.com/post/5864951375Thu, 26 May 2011 09:43:53 -0400<img src="http://25.media.tumblr.com/tumblr_l8pa0i1mQW1qcm4r3o1_500.jpg"/><br/><br/>http://rocksrock.tumblr.com/post/5859643735http://rocksrock.tumblr.com/post/5859643735Thu, 26 May 2011 03:03:33 -0400<img src="http://24.media.tumblr.com/tumblr_l8urj9Cd2i1qa5bbmo1_500.jpg"/><br/><br/>http://rocksrock.tumblr.com/post/5859613754http://rocksrock.tumblr.com/post/5859613754Thu, 26 May 2011 03:01:24 -0400<img src="http://25.media.tumblr.com/tumblr_lfo0q1jcRx1qgzn5jo1_500.jpg"/><br/><br/>http://rocksrock.tumblr.com/post/5847536328http://rocksrock.tumblr.com/post/5847536328Wed, 25 May 2011 19:36:53 -0400<img src="http://24.media.tumblr.com/tumblr_llqmirOqoo1qkzvtmo1_500.jpg"/><br/><br/><p><a href="http://therockymineralshow.tumblr.com/post/5835121137">therockymineralshow</a>:</p> <blockquote> <p>Ajoite</p> </blockquote>http://rocksrock.tumblr.com/post/5835280836http://rocksrock.tumblr.com/post/5835280836Wed, 25 May 2011 12:15:12 -0400<img src="http://25.media.tumblr.com/tumblr_llqrj1xnHm1qjcm2oo1_500.jpg"/><br/><br/>http://rocksrock.tumblr.com/post/5834914103http://rocksrock.tumblr.com/post/5834914103Wed, 25 May 2011 11:57:46 -0400<img src="http://24.media.tumblr.com/tumblr_lks8vrXAjp1qgzn5jo1_500.jpg"/><br/><br/><p><a href="http://mineralia.tumblr.com/post/5774402122">mineralia</a>:</p> <blockquote> <p>Rosasite with Conichalcite from Mexico</p> </blockquote>http://rocksrock.tumblr.com/post/5834742778http://rocksrock.tumblr.com/post/5834742778Wed, 25 May 2011 11:49:05 -0400<img src="http://25.media.tumblr.com/tumblr_llg9p5mZwR1qgzn5jo1_500.jpg"/><br/><br/><p><a href="http://mineralia.tumblr.com/post/5834668148">mineralia</a>:</p> <blockquote> <p>Dioptase with Calcite from Namibia</p> </blockquote>http://rocksrock.tumblr.com/post/5834731261http://rocksrock.tumblr.com/post/5834731261Wed, 25 May 2011 11:48:29 -0400
