I remember reading about Graphene for the first time a few years ago. What got me interested more than the concept of making something that is 1 atom thick, was the manufacturing process.

Several universities that wanted more of the material to study and experiment on, hired students from the campus to sit down with some coal and duct tape, and simply tape and tear the coal as many times as possible.

After a certain amount of taping and tearing, to the piece of coal and to the tape itself, all that would remain stuck to the tape was a single layer of carbon atoms, or, Graphene

The wikipedia article calls it "Mechanical Exfoliation".
