Interesting tidbit... bucky balls are now essentially 'illegal'.
They can no longer be sold in the US, and the manufacturer is required to recall all bucky balls still out in the wild.
I don't think I'll be turning in mine, but I just thought this little fun fact went along with the story.
magnets are an extremely dangerous swallowing risk. 2 magnets can attract through the intestinal wall and very easily tear the tissue. Scary shit.
I have a friend that worked on the recall for the consumer product safety commission and said it was a pain to do. It was one of the only products he's gotten flak from retailers when he would visit them.
Anyhow though, the product Bucky balls had the recall, but you can still get get generic neodymium magnets on Amazon. (And you don't have to return them if you already own them.) I bought some square ones for my dad - he already had BB. And really, when I got my own BB years ago, I knew right away not to let my kid play with them and took them to my office. Don't people think about what they're doing anymore?
Haha I use bucky balls too. I use them to store my little strips of kanthal and braided wire for my weeks coils. You can also put one or two on the tips of your scissors to grab the clippings. Holds them perfectly, and I no longer find little clippings everywhere. I keep my massive spools in the closet and just break them out every other week or so.
