Aerogel is nicknamed "frozen smoke" and is made by extracting water from a gel made from silica or another metal oxide, then replacing it with a gas such as carbon dioxide.
Aerogel, one of the world's lightest solids, can withstand a direct blast of 1 kilogram of dynamite and protect against heat from a blowtorch at more than 2,400 degrees Fahrenheit.
NASA originally developed aerogels for work in space, but companies are finding plenty of uses for them here on Earth.
Their low thermal conductivity makes them superb insulators, But it’s their extreme absorbency that might come to the rescue in an oil spill.
