Is it possible to create green fire?

There are many website that give different tips on how to change the color of fire. I found this one that gives tips to have a great looking campfire. You can check it out here. http://www.tentandtrek.com/2006/09/18/make-cool-campfire-colors-make-colored-flames-for-your-campfire/ I have never used any of the tricks listed there. My family and I like to use copper tubing and an old garden hose. Here are some in depth instructions on that. It is very easy and fun to watch the different colors. http://www.articlesbase.com/nature-articles/add-a-touch-of-colour-to-your-camp-fire-193985.html I hope you enjoy watching the beautiful colors from your fire!
