Racing Level Particles

For my first particle I want to make high pressure steam that would be escaping from the pipes in my level onto the track.

It would look very similar to the steam in this video but the color would be slightly yellow because it's an old gross space station and there is already some yellowish fog at the very bottom of the level.

I used this tutorial for making an easy smoke texture in photoshop: http://www.youtube.com/watch?v=1GmlIfTsRaQ

For my second particle I want to make little lightning/electricity sparks to replace the temporary UDK particles on my exploding barrel.

I would want it to look similar to what is coming off this Tesla coil but smaller, more of them, and probably a different color.

I'll probably reference this video that explains how to make a simple version of what I want: https://www.youtube.com/watch?v=DjLi8I9mCuU
