View Full Version : The Attraction of the Light

Hey guys,
When the light went off in my apartment I took this little candle to make some light and the candle wasn't used in quite some time so it probably had dust on it or who knows what but they looked like small paces of paper.
The small peaces actually move towards the light wile fire consumes the candles oil than they get pushed away and back inside again. Its probably nothing new its just interesting to see their motion how they move seems inspiring and thought of sharing it here and see what you guys think.

Here's the video:

Looks like electrostatic repulsion/attraction to me. The flame is positively charged and induces an opposite negative charge in the dust or paper. Once the particles have an opposite charge, they start moving toward the flame. When they get close enough to the flame a positive charge is induced which causes them to repel the flame. This process keeps repeating itself so that the particles move back and forth in a balanced state.

I'm just speculating.

It could just be convection?
