Workshop for students from Kanagawa University

I gave one more workshop for students from Kanagawa university, Japan. Today, I tried something new, instead of working on C₆₀ for each student, I asked them work on two zeolite structures, zeolite A and Faujasite, together after making the famous 30-ball Sangaku problem, which just gave them enough beading experience to move on. Both of these two zeolite structures consist of the same structural unit (Secondary Building Units, SBUs), namely truncated octahedrons. It seems to be easy for them to work together, then combine them into these two framework types. Here are a few pictures from the workshop.

Students were very happy when they succeeded in making the zeolite A.
