Singing candle
From Wikipedia, the free encyclopedia
A singing candle is an electro-acoustic installation. The movements of a candle flame are transformed into sound by means of a light dependent resistor (LDR). The sound waves, in return, have an influence on the flame, through an amplifier and loudspeaker.
The project posits the possibility that the chaotic system may reveal some kind of telepathic effect, where the thoughts or state-of-mind of the observer seem to influence the system.
