What do you get when you combine electrical science and Tchaikovsky? A geeky way to show some holiday spirit! The video below features two solid state Tesla coils performing “Dance of the Sugar Plum Fairy” from Tchaikovsky’s The Nutcracker. Believe it or not, the sparks that you see in the video are the source of the sound you’re hearing. Tesla coils produce electricity at such a high voltage that when the device discharges, the electrical energy is released into the air as heat, light, and sound. Using proper equipment, one can play a Tesla coil like a musical instrument! For a more detailed- and techier description- of how to get a Tesla coil to sing, this video is excellent.
