Flames and smoke, how do you make it?

Flames and smoke, how do you make it?

Hey gang, I have spent a fair amount of time on here catching up and looking at all the cool stuff and earmarking ideas I want to steal in the near future! Something I have not found is how you guys make your smoke with the colors on it. What material do you use for smoke and I am assuming you use a spray can of paint to add color..


I realize this is not rocket science but it is one of the things I have not modeled before. Has anyone given a tutorial with pictures somewhere here in the forum?  If not, would someone be willing to do so in the near future?

I am still considering making a static display at our next model trains show and I want to add some fire and smoke to the display.

thanks
