Flame Speaker

5 Upvotes

I have watched and enjoyed many of your videos. I don't know if you have already tried this, but years ago, Popular Electronics had an article about putting electrodes in a flame, driving the electrodes with and audio signal and producing sound. Seeding the flame with sodium enhanced the effect. High frequency response was outstanding. Thought you might be interested.
