Scientists in Australia have found a way to make graphene, a carbon material one atom thick, using soya bean oil.
Graphene is amazing: it's more flexible than rubber, 1 million times thinner than a human hair, more than 200 times stronger than steel, and it can conduct heat and electricity.
Researchers think graphene could help revolutionise medical technology, electronics, transport and energy. But at the moment it's too expensive to produce.
Hopefully this advance will make graphene cheap enough to start transforming our technology.
