Note that this isn't a true Buckminster Fullerene, since magnets are dipoles while carbon atoms are quadrupoles. True buckyballs have hexagons and pentagons, while ours has squares and is slightly smaller.
The big challenge: start with two pentagons, then assemble two hemispheres. (This is how it happens in nature.) Then knit the two hemispheres seamlessly together, trapping a glass marble or other gigantic ionized metal atom within. It's harder than it looks!

By the way wbeaty- I think your videos are fantastic; been watching them over the past week or so. You'd make a great teacher! keep up the good work- it doesn't go unappreciated:)
Also, they apparently form as 30-carbon hemispheres. The two "clamshells" find each other and snap together to form a sphere. If ions of other elements bonded to the cleft in one hemisphere, then you end up with a caged ion trapped inside.
You can create this process with the magnets, though there's a trick to it.
yes- I've heard of intercalated fullerenes. They can also be used to cap carbon nanotubes, and they can even trap bucky balls in a nanotube providing there's a large enough diameter; so-called nano pea-shooters and pea-pods. A research group in my department are doing all sorts of wonderful things with nanorods and fullerenes. Fascinating stuff!

N50 is the magnetic strength of the material. But smaller magnets are also weaker. If you buy tiny magnets, N35 magnets act weaker.
