One box of Girl Scout cookies worth $15 billion

As a chemistry teacher, hearing the quote "carbon is carbon" about 1:20 into this video just made my day.

In the video researchers from Rice University Labs turn girl scout cookies - trefoils from what I can tell - into graphene on copper, and the girl scout troop then performs some simple tests on the graphene sheet, clearly testing the conductivity (or resistance, maybe) of the product.
