Roger,
I'd like to try some of those spheres out for our magnetic field  
display.  We use iron filings and they do leave residue on the user's  
hands and seem to travel around the museum as well.
By the way, the Flying Magnet display sits in out entryway, the first  
thing that is seen by visitors and receives lots of stare time as  
they try to figure out how one magnet "passes right through"  
another.  Thank you again,
Tom Tanioka
