Buckyballs

These are my sons Buckyballs. It is made of 216 strong neodymium rare earth magnetic beads and cubes.
Fascinating toys, also for adults. The things you can make with it are almost similar to the Buckminsterfullerene.
The manufacturer stopped producing this toy, because of what they call "baseless and relentless legal badgering". That is really a pity, because it is fascinating what you can do with it and how it feels in your hands.
It is a toy you wished you bought it sooner. Now it is (almost) too late.
