Scientists have developed a solid material so light it can be balanced atop the petals of a flower.

Researchers from Zhejiang university in Hangzhou, China, showed off their newly developed graphene aerogel by balancing a block of the stuff on a delicate cherry blossom.

The sponge-like matter is made of freeze-dried carbon and graphene oxide and is the lightest solid material in the world.
