Hi all, Forgot to mention, in the Handbook of Chemistry & Physics, circa 1988, for diamagnetic materials, the (s) symbol means "solid", and the (l) symbol means liquid. This note was forwarded to me by Robert Lamb. One could delve forever with different materials, but I would think, the carbon and bismuth are the more cheaper and less toxic materials for levitation. For those interested in more extensive experimentation, I would suggest checking out this commercial web site, for more magnets: http://www.wondermagnet.com/dev/magnets.html The items #9, #10 and #13 would all work and are bigger than the Radio Shack pill magnet. I only got the #13 (a ring neo) from this site. One has to go to the ordering info, to check on availability. The ring and disk neo's are alot easier to levitate. Their is one curved neo, that might interest the traditional coil/magnet crowd, there too, but mounting two such magnets could be somewhat of a challenge to keep them apart. Check out the humor pictures, and references to other sites. Its worth the time to browse and see.
