Amazing Singing Candle

We loved this video and the candle too!

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
Camptown Races
The Star Spangled Banner
Jingle Bells

The inventor wrote that he hoped the viewers of his video found it "funny and fascinating".

We most certainly did. :)
