The fun part about Buckyballs is the way they balls arrange themselves when you stick them together. The balls have a preference for certain crystalline structures. There seems to be a huge variety of structures the balls like to arrange themselves into, as you can see in the video above. (Learn other tricks with Buckyballs.) When I play with them, I feel like my hands are a nanotechnology machine sticking atoms together.
I got a set of these magnets from the hubby for Christmas, and since he liked tinkering around with them so much, that I bought him a set as well. I actually almost bought the Buckyballs for him in the first place, but opted for other fun items. 
They are addictive to play around with, and yeah, your fingers do get sore from prying the magnets apart because their pull is rather strong. I once made a bracelet out of the set and wore it when I went out (just to the mall, post-Xmas with the fam, nothing special). I’ve kind of set them aside for now, but whenever I need a simple toy to play with, I’ll get them out again.
