goldnugget77,
i don't belive there somthing worth while in this nuts...

PreciousMexpert ,
the cigar box is the same idea, just different housing...
find your self a good looking 12V fan... the magnets will not effect it.

Could be that the weight of the magnets overpower the fan motor, they don't have much horsepower and may not be able to spin the increased weight.

Maybe smaller magnets from laptop hard drives will work.

I've got a Corning PC-351 hotplate/stirrer and it has a small fan/stirrer motor that is about 3"x4"x2" with a 1/4' shaft to run the stirrer and cool the unit. Thats why I don't think the fan is big enough to spin the magnets.
Mine will spin a 1/2" x 2" spin bar in a 2L flask and really mix it up.
