I don't know how many of you are familiar with buckyballs (the little magnets sold in 6 x 6 or 5 x 5 cubes), but once you start playing with them it is hard to put them down. I had received a 6 x 6 silver set last year for Christmas, so when I ( I say 'I' when what I really mean is my husband whom I stole these from) got two more 5 x 5 blue sets this year, I couldn't wait to explore the new possibilities available to me.
Bucky (the mouse, named by my husband when he got home and saw what I had done) was born out of "hmmm, I wonder what happens if I do this," and a lot of trial and error. After all, the magnets often have a mind of their own. Here's how you can make a mouse of your own.
