Noble Prize laureate Konstantin Novoselov says that making Graphene is easy: all you need is a mobile phone, Graphite from a pencil and a scotch tape. You stick the tape to the Graphite and transfer it to a solid substrate, the mobile phone's screen in that case. He also says that Drinking Vodka can help as it can degrease the surface.
