When I was in Wal-Mart this evening, I walked passed a box of Borox and decided to pick it and a bag of Epsom Salts up. We'll be having yellowish/light green (Borox) and white (Epsom Salts) campfires this summer. I save toilet paper rolls, plug one end with news paper and put a few table spoons of either one of these in the middle and plug the other end with newspaper. When the kids are smores'd out and no more cooking will be done on the fire, I sneak one of these in with a log and listen for the kids to ooh and ahh. Some folks soak pine cones in a mixture and just toss them on as well. You can make a ton of different colors by adding different chemicals.

Remember, use small quantities and don't cook over the fire after tossing the chemicals in to it.
