The Mid‑America Science Museum in Hot Springs, Arkansas is home to the world’s most powerful conical coil, a giant Tesla coil that produces 1.5 million volts and holds a world record for its extraordinary electrical output. The high‑voltage coil, known as “Caged Lightning,” is exhibited inside a massive Faraday cage that ensures visitor safety during electrifying demonstrations.
Dedicated on November 19, 2002, the exhibit showcases one of the most impressive applications of Nikola Tesla’s transformer technologies, captivating audiences with spectacular displays of purple plasma arcs and crackling electrical discharges that evoke the inventor’s early experiments with high‑frequency currents.
Visitors to the museum can witness this record‑setting coil in action during scheduled shows, where the machine generates intense electrical fields within its protective enclosure — providing both an educational and thrilling experience for science enthusiasts of all ages.
The Mid‑America Science Museum’s powerful conical coil not only highlights the legacy of Tesla’s pioneering work in electrical engineering, but also stands as a unique world‑record attraction in the heart of Arkansas.
