Researchers Make Graphene From Girl Scout Cookies 129
An anonymous reader writes "Last year we learned that the miracle material graphene could be made from common table sugar, and now researchers at Rice University have taken the discovery one step further by literally baking it from a box of girl scout cookies. A group of graduate students led by chemist James Tour recently teamed up with Houston Girl Scout troop 25080 to perform the feat using a single box of Trefoil cookies — which could potentially yield $15 billion worth of graphene."

This is equivalent to someone inventing a process for producing super-high quality silicon from sandy mud without purification steps. Currently, only the highest grade of silica can be used for manufacturing of that type.

Another interesting fact along the same lines is the cap on the Washington Monument [wikipedia.org] is also made out of aluminum for the same reason. To quote the Wikipedia article on the Washington Monument:
it was finally completed, with the 100 ounce (2.85 kg) aluminum tip/lightning-rod being put in place on December 6, 1884. The tip was the largest single piece of aluminum cast at the time, when aluminum commanded a price comparable to silver. Two years later, the Hall–Héroult process made aluminum easier to produce and the price of aluminum plummeted, making the once-valuable tip nearly worthless
