These Russian scientists working at the University of Manchester took graphite from a pencil, then slowly, but surely peeled off, thinner and thinner layers with Scotch Tape, and voilá; A Nobel Prize!
Actually it is more complicated, but that is the essence of what they did, and led them to a great finding: Graphene!
A friend of mine, made a pencil drawn circuit that actually conducted electricity, he did not pursue that observation though, and did not get a Nobel; next time Jim!
