A candle flame flickers because the air around it moves in little waves. Imagine you're blowing on a small fire, sometimes the wind is strong, and sometimes it's weak, making the fire waver like a smile. The hot air from the flame rises up, pulling cooler air underneath it, causing the flicker.
Examples
- A candle flickers like a happy fire when you blow on it.
- The flame wobbles if there’s a draft near the window.
- It dances more when the room is cold.
