Guessed? This new unique invention
Chinese scientists have developed the lightest material in the world.
It consists of lyophilised graphene oxide and carbon.
Developed spongy material graphene airgel weighs 0, 16 mg / cm3,
he freely rests on flower petals.
But this is not the only advantage of graphene.
Despite its lightness, graphene is incredibly durable.
Also, the material is flexible enough, and yet he is able to filter
water, holding a variety of liquids and gases.
