Formation “only possible in lab settings”? I thought the way to make buckyballs was to burn the carbon rods on an arc welder into oblivion, then sift through the debris looking for the Buckyballs you accidentally made without realizing it? Seems like a plausible scenario that could occur anywhere (edit: and wikipedia suggests even occurs in lightning strikes and candle flames.) Didn’t the original paper lead to a corresponding world shortage in electric arc welders, for a time, as labs bought them all up?
