Graphene Aerogel, the world's lightest material ever made

Researchers from China's Zhejiang University developed a new sponge-like solid material (which they call Graphene Aerogel) made from freeze-dried carbon and graphene oxide which they say is the lightest material ever made. It's so light it can be placed on the delicate petals of a cherry blossom:

Aerogel weighs just 01.6 milligrams per cubic centimeter, just twice the density of hyrdogen.
