Lightest material on earth: Graphene Aerogel Graphene aerogel is so light that an cubic inch of the material can be balanced on a blade of grass, the stamen of a flower, or the fluffy seed head of a dandelion. Because of its low density, Graphene aerogel has the ability to absorb up to 900 times its weight in petroleum. This material will be useful for cleaning up oil spills in the future. The American Chemical Society said in 2012 that graphene was discovered to be 200 times stronger than steel and so thin that a single ounce of it could cover 28 football fields. Chinese scientists have created a graphene aerogel, an ultralight material derived from a gel, that is one-seventh the weight of air 🌬
