The C60 buckminsterfullerene model, a.k.a. geodesic truncated icosahedron happens to be also the design of the traditional soccer ball.
You can already purchase the connectors for $3.50, shipping included anywhere in the world.
Or cut your own, using the free design. You can even sell those! it’s CC-by-sa!
Just use plain coffee stirrers to build the 12 pentagons and 20 hexagons.
Design for build and for the connectors is CC-by-sa Yama Ploskonka 2014
to build a model of the C60 buckminsterfullerene, you will need:
- 60 120-degree connectors. Buy them here
- 100 coffee stirrers. If you want your Bucky ball to be 2-color, get 60 of one color (black in the example) and 40 of another (white in the example). The project might be rather large unless you cut the stirrers. All stirrers must be the same length. When using more than one color, you may want to check that they have the same “give”. Otherwise, if some are more rigid they will distort your pseudo-sphere
- connect one black stirrer to one connector – repeat 59 times
- form a pentagon, by connecting 5 stirrer-connector pairs end to end. Repeat 11 times
- Connect one white stirrer to the end of each free connector in one of the pentagons – that will be 5 stirrers. Repeat with one other pentagon. One of these pentagons will be the base, the other the top.
- Connect one white stirrer to the end of one connector in another pentagon. Repeat 2 times, in adjoining connectors. That will be 3 stirrers. Repeat with all other pentagons, to a total of 30 stirrers
- Connect one of the free connectors to the end of a stirrer attached to the Base pentagon (one of those with 5 stirrers). Repeat with 4 more pentagons.
- Do the same with the Top pentagon. That will be 5 pentagons
- In each section, Base and Top, connect the pentagons to the corresponding neighbor, using the closest stirrer to each
- Attach Base and Top sections
Let me catch some Zs and I will add pictures for a step-by-step later

- Wikipedia pages on buckminsterfullerene, about the truncated icosahedron, and just for lulz the badly sourced and wrong data Wikipedia page about the soccer ball
