“It would take an elephant, balanced on a pencil to break through a sheet of graphene the thickness of cling film.”
said Columbia University Engineering Professor James Hone; continuing, "Our research establishes graphene as the strongest material ever measured, some 200 times stronger than structural steel."

A graphene sheet is only one atom thick, so it takes 3 million sheets on top of each other to be the thickness of one millimeter!
It is so strong because it is made of Carbon atoms double-bonded together in a lattice. “It would take an elephant, balanced on a pencil to break through a sheet of graphene the thickness of cling film.”
