Hundreds gathered at the Thessaloniki Science Centre and Technology Museum on November 4 to enjoy a concert performed by a giant Tesla coil.
The video shows sparks coming out of the 4,5 metre high device being modulated to recreate musical pieces.
"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.
