Wolfgang Kratschmer (Max Planck Institute for Nuclear Physics, Heidelberg, Germany): "We stumbled over the soccer ball-shaped C60 molecule when we produced soot in order to investigate whether such dusty material occurs in interstellar space. It may be interesting to note that H.W. Kroto [University of Sussex, England] and R.E. Smalley [Rice University, Houston], the actual discoverers of this unique molecule, started their work with a very similar objective.

"Our contribution to this field is the discovery of an exceedingly simple and efficient method to produce C60 and other closed-cage carbon molecules, such as C70, in bulk quantities. The properties of solid C60 known...
