Hundreds gathered at the Thessaloniki Science Centre and Technology Museum on November 4 to enjoy a concert performed by a giant Tesla coil. <br /><br />The video shows sparks coming out of the 4,5 metre high device being modulated to recreate musical pieces. <br /><br />"As the organizers explained, the coil can produce different tones by modulating the number of the sparks that the coil emits. What appears to be a continuous burst of sparks is actually a specific number of sparks generated per second," the filmer wrote.
