Abstract
The plasma globe or plasma ball is an underutilized resource for teaching the physics of electricity. It also offers a convenient source of electric field that can be used for demonstrations and experiments. Unlike the Van de Graaff generator, the plasma globe does not shock you and is essentially silent. Other authors have written up some of these activities, but the full potential of the plasma globe is generally not taken advantage of by most teachers. I hope that this article can bring more awareness to how this ubiquitous piece of novelty lighting can be an essential physics teaching apparatus.
