........I don't get it. What's illegal about magnets?
Also, I was hoping you were going to do something cool with the magnetic properties. Like rolling it down a path where it passes by other magnets that are fixiated to a stable point, but the magnetic properties cause them to push off each other, means the round one on the path is always rolling in a circle or something.
I mean it looks pretty, but I was hoping for a sciency showoff.
