Ah the tesla coil. Invented by Nikola Tesla around 1891. Technically speaking, “it is used to produce high voltage, relatively high current, high frequency alternating current electricity.” Although its traditional use includes conducting experiments in electrical lighting, x-ray generation, and other high frequency alternating current phenomena, today tesla coils are constructed and used by enthusiasts for our entertainment. With proper manipulation, the electrical current can display a wondrous light show and even spark to a specific song (in this video, the Zelda theme). This particular tesla coil professional adds to the excitement with balloons that pop after being ignited with fire. Cool stuff.
