C420 Fullerene Model
This is a large model of a C420 "fullerene" molecule built by the Stony
Brook University Chemistry Club.
It is assembled from many plastic
tubes and metal connectors.
I designed it as a fairly close approximation to a sphere
with the constraint that only two lengths of edge are used.
Groups of students made modules in parallel, being careful not to mix
up long and short edges.
It hangs from five strings. The 50-inch diameter was too wide for the
so we carried it in two halves from
the lab to the Chemistry Library.
Here's the whole happy crew. As far as I know, the model is still
hanging in the library.
