Aerogel is currently the lightest known solid material in existence. 99.8% of the volume is empty space within a fine silica structure. It also has the lowest thermal conductivity of any known solid, which means it makes a great insulator.

First created as a result of a bet, aerogels are a group of materials in which the liquid portion of a gel has been replaced with gas.

NASA has even used Aerogel to collect interstellar dust particles due to its high porosity.
