Burning candle snuffed
Smoke trail rising
Wick's heat dissipating
Wax cooling slowly
Solidifying the candle again
No sparks
No flames
No heat
Just candle
Just wax
Just wick
Except
The wick is burnt
Shorter than it used to be
The wax's mass decreased
Transformed and floating away
The heat travelling elsewhere
Away from the candle's reach

Flames light
Flames flicker
Flames fade out
Flames swirl with energy
Candles don't
