Several readers have asked how I achieved the rainbow fire effect with this Halloween jack-o-lantern. It's very simple! Here are written step-by-step instructions for you, plus a video. Make a Rainbow Fire Jack-o-Lantern | Watch the Video
You'll get the best success if you apply the alcohol liberally. Glop on the hand sanitizer. Drizzle extra methanol all over everything. The alcohol will pool around the base of the pumpkin, so you need to expect fire on your surface. It's an alcohol fire, so it burns off quickly. Just make sure you don't perform this project near anything flammable.Feel free to experiment with colorants. You could add copper sulfate, borax, lithium or strontium salts, calcium or even storebought smoke bombs or sparklers for added panache.
If you are lighting the pumpkin indoors, I recommend setting it on a cookie sheet, which in turn rests on a potholder. If you are setting the pumpkin alight outdoors, avoid placing it on dry grass. I filmed the video with the pumpkin sitting directly on my kitchen countertop. I'm not saying you should do the same -- just pointing out that the project is not particularly hazardous if you exercise caution and control. Have fun!
