Aerographite: Lightest And Least Dense

The density of aerographite is 0.2 milligram per cubic centimeter making it the lightest and the least dense material in existence. On the nano level it looks like a network of hollow carbon tubes. Talking about the structural qualities, one can compress it to 1,000 times smaller, and itâll get back once let go. Created by researchers at Hamburg University of Technology and the University of Kiel, this stuff can support over 40,000 times of its own weight.
