Candlelight Observation
- Starting small and short flame to long flame.
- Without any interruption, the flame is quiet and peaceful but still moving a little.
- Sometimes the flame makes dark and thin smoke.
- small wind or breathing make the frame short and round.
- Blowing out a candle is harder than I thought.
- Flame has a quite tenacious life
- When the frame disappeared, the candle wick burned a little bit more and fade out.
