The writers describe an activity that explores molecular geometries using magnets, paper clips, and ball bearings. In the activity, magnets were used as electron domains and a ball bearing as a central atom. One of several advantages of using this magnet model was that it facilitates swift interchangeable geometries. These models are great to use as a hands-on activity in the general chemistry laboratory.
