When you think ‘aerogel,’ think unbelievable

When you think ‘aerogel,’ think unbelievable - The most expensive chemical substance known to man, more than safron, etc. For example: “Silica aerogel holds 15 entries in the Guinness Book of Records for material properties …” and “it is very strong structurally, able to hold over 2000 times its own weight” oh … it’s “90-99.8%” air, so it’s also almost transparent. Unreal.
