In Mr. Dougan's computer classes, students saw with their own eyes how electricity travels without wires -- wireless electricity. When a lightning machine is touched, electricity becomes grounded giving it a path of least resistance to travel through. This process shows how information can be sent through air, or in other words, how electricity travels wirelessly.
