Aerogel is a manufactured material with the lowest known density of any solid. It is derived from a gel in which the liquid component of the gel has been replaced with a gas. The result is an extremely low-density solid with several remarkable properties, most notably its effectiveness as a thermal insulator and its extremely low density. It is nicknamed frozen smoke, solid smoke or blue smoke due to its translucent nature and the way light scatters in the material; however, it feels like expanded polystyrene (styrofoam) to the touch.
Aerogels are produced by extracting the liquid component of a gel through supercritical drying. This allows the liquid to be slowly drawn off without causing the solid matrix in the gel to collapse from capillary action, as would happen with conventional evaporation. The first aerogels were produced from silica gels. Kistler's later work involved aerogels based on alumina, chromia and tin oxide. Carbon aerogels were first developed in the late 1980s.
No, water is not the lightest liquid on Earth. Liquid hydrogen and liquid helium are lighter than water because they have lower densities.

The heaviest materials on Earth are typically found in the Earth's core, such as iron and nickel. The lightest materials, like gases such as hydrogen and helium, are found in the upper atmosphere and in outer space.
The lightest gaseous element is hydrogen, with a density around 7% that of air; The heaviest is radon, with a density of around 8.5 times that of air.Radon is radioactive, and relatively short lived; the heaviest stable element is xenon, with a density around 4.5 times that of air.
gas is the lightest in weight
The lightest alkaline earth metal is Beryllium(Be) having atomic mass 9.012 dalton. The heaviest element in this family is radium.
The state of matter of hydrogen, which is the lightest element, is that of a gas at room temperature. Hydrogen also is very flammable gas.
