Abstract | Presents an easy and inexpensive method to demonstrate VSEPR theory that involves the use of only a ring stand, clamp, cow magnets, and a ball bearing. Has the advantage of producing a series of models using invisible magnetic repulsion forces to show the orientations occurring in molecules where similarly invisible electron repulsion forces are at work.
