If magnetism is part of your curriculum, this is a quick, clean way to demonstrate and visualize magnetic fields!

The demonstrator is a transparent acrylic case that holds iron filings suspended in a fluid of mineral oil.  Place a magnet over it and the field pattern can be viewed directly.  It can also be placed on an overhead projector for display to the class.
