The 1.5-million-volt conical Tesla Coil in operation at the Mid-America Science Museum in Hot Springs (Garland County) is billed as the most powerful in the world. Its inventor, Nikola Tesla, is recognized by many as the “father of electricity.” The museum uses the coil, known as “Caged Lightning,” in a “Sermon from Science” program to educate the general public about Tesla’s work and inventions.
