To make a fake fan-style fire, I'd need three main elements. First, some very lightweight silky material to act as the flame. Second, a fan would need to be placed underneath of the silk, blowing up on it. This, hopefully, would create a fire-esque flapping effect. Lastly, the material needs to be lit in fiery colors. With these three elements put together well, a pleasing fire effect is possible. Some executions of this technique are more successful than others. I was hoping for mine to be, at the very least, not terrible.
I wasn't too sure how I wanted to go about constructing it, so I decided to work on the design in CAD using Sketchup before proceeding. I did decide fairly early on, however, that I wanted to use a typical box fan
