Aerogels are a group of materials in which the liquid portion of a gel has been replaced with a gas. It was first created as a result of a bet. This sample consist of 25mL of silica aerogel particles. It is safe to touch, but may leave sticky residue. 

Being the lightest solid material know, aerogels are up to 99.8% air. Its also has the lowest thermal conductivity of any know solid. 

Due to their high porosity, NASA has even used aerogel to collect interstellar dust particles in outer space.
