Tesla Coil

The spectacle and science of indoor lightning is provided by the 20-foot Tesla coil suspended overhead. Observe from reclined benches as the coil puts on a 1.5-million-volt show of electrical discharge, with arcs jumping up to 10 feet from the center coil to the grounding rings. Explore the properties of electrical charge and magnetism as you learn how the Tesla coil builds up and releases such massive amounts of energy.
