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.
