The world has new lightest solid material. That is just twice the density of hydrogen and this is enough to break the Guinness World Record.
Last year, German scientists created aerographite, which won "the world's lightest material" title at 0.2 milligrams per cubic centimeter. However, a team from China's Zhejiang University that has created Graphene Aerogel - a sponge-like solid material made from freeze-dried carbon and graphene oxide that weighs just .16 milligrams per cubic centimeter has now eclipsed them.
To demonstrate just how light it is, Zhejiang University in China, where the material's creators are based, has published pictures of chunks of it perched on small leaves, held aloft by grass seedheads and floating on the stamen of a cherry blossom.
