Flame with sparks.

Using a cube as both the emitter for the liquid container, and simultaneously as an emitter of nParticles that i was using to represent sparks.

The n particles are too small and un noticeable at the moment, especially in the final render.

The scene has three expressions running in it, one for the wind direction for the nucleus responsible for the n particles, one that changes the initial velocity of the liquid to simulate it being under the same wind effect as the nParticles, and one that changes the turbulence of the liquid to make it more natural looking.

Using the opacity graph i shaped the flame, using a slightly broader and longer flame than the candle.

Using the incandescance controls i linked it to the temperature of the flame, so the flame has realistic shading.

I wanted to make the flame have these small bits of flame left behind when it moves fast,  like in the top of the image but the effect is hard to reproduce and often looks bizarre.
