Singing Candle- Weird Science Experiment- Magic Trick

YouTube via OrganicVeggieLoaf | January 30, 2008

"This video, recorded in 1997, demonstrates an early proof of concept prototype I put together for a novelty entertainment product I called the Singing Candle, or CandleSpeaker (please observe copyrights). The candle flame sings the following melodies:
1. Strolling Through the Park One Day
2. Shave and a Haircut
3. Mexican Hat Dance
4. Camptown Races
5. The Star Spangled Banner
6. Jingle Bells

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 final product was going to sing with a human voice via amplitude modulated ultrasonic carrier, and not with the cheesy squarewave oscillator signal used in this video. You won't see this in stores anytime soon, however, as the project never really got off the ground.

But here I am talking to a candle flame and it's kind of funny and fascinating. Hope you think so too.

BTW, The accent in my voice is fake- I did it just for fun. You know how it is, when you're goofing off at home all alone?

Recorded at Batchelor Pad Heaven in 1997. Davis, CA.
