>Tappers, I just finished making what I think is a cool idea for the
>3/4" spherical magnets.
> I took a couple of feet of 1.5" ID acrylic tube and machined caps
>for the ends. Then glued a 1/4" x 1.5 circle of Sorbathane to the caps.
> Inside the tube I put a length of 1" x 1" x 1/8" Aluminum angle and
>a Spherical magnet.
> "Ta Da" I have a lens law tube that can be passed around, that the
>students can see up close and personal.
> More importantly the little beggers can't swipe the magnet, lose
>the magnet, or worse get it covered with debris from the floor.
> I post a photo Vacek's site. Zig
