tape over the area7. When you pull up the tape,youll see that it pulls up a thin layer of some of
the shading from your pencil. That layer is called graphite,one of the softest minerals in the world.
Now stick the same piece of tape on another sheet of paper and pull the tape up there should be an even thinner layer,this time left on the paper. Now imagine that you do this over and over,until you get the thinnest possible layer of material on the paper. This layer would be only one atom thick,and you wouldnt be able to see it. Graphite is made of layers of graphene,so when you get to the thinnest possible layer,youve found graphene.
