<p>This is my original green fire tutorial. These flames are bright apple green, simple to produce and long-lasting.</p><p>If you prefer to be shown exactly what to do, I&#39;ve got you covered. Here is a video tutorial for making green fire.</p><p>I usually use borax or boric acid to make green fire, since it is inexpensive and readily available in many places as a disinfectant powder or roach killer. However, copper ions also emit green light. This is another super easy way to make green fire. If you use copper sulfate with a gel fuel, you can get a green flame that lasts for several hours.</p><p>Green fire is a nice effect all on its own, but it also makes for a cool Halloween jack-o-lantern. The effect is eye-catching, don&#39;t you think?</p><p>This is a tabletop fire project that shows how tornadoes and fire whirlwinds form, except I colored the fire green! Of course, you could make the fire any color you like.</p><p>Spritz a chemical into a burner flame to produce colored fire! Yes, you could do this just for fun, but the most common use of this project is as a chemistry demonstration, to capture student attention and to explain excitation spectra.</p>Just about anything flammable can be made to burn with a green flame. This includes pinecones, which you can burn on their own or add to a campfire or fireplace for a festive touch.
