Aerogels are the lightest weight of the known solid materials. They are extremely porous and have extraordinary thermal insulation abilities. The lightest aerogels have a density only about three times that of air. A block the size of a person weighs less than one pound, and looks like it would blow away in a slight breeze. Yet it is able to support the weight of a subcompact car. Aerogels are formed by dispersion of a gas in a solid or liquid. Aerogels can be thought of as the reverse of aerosols.
