The video was recorded in 1997. According to its inventor the Singing Candle was a "concept prototype" which never got off the ground.
How It Works:
This is basically fire modulated with a high voltage audio signal, similar to the techniques used to create a plasma tweeter or plasma speaker using a tesla coil or CRT flyback transformer. There is no speaker- the sound comes from the rapid air pressure disturbances in the candle flame itself, controlled by a high voltage current modulated with an audio signal and passing through the fire plasma.The songs the candle sings:
Strolling Through the Park One Day
Shave and a Haircut
Mexican Hat Dance
The Star Spangled Banner
The inventor wrote that he hoped the viewers of his video found it "funny and fascinating".
We most certainly did. :)
