How to make a green flame in a campfire

While cutting brass and copper fittings with a chop saw the metal was self sustaining and melted emmiting a green flame until metal was gone.

I like to mix flash powder in a bottle of water and I pour it over the campfire prior to lighting it, being sure I splash it around the unlit fire instead of pouring it directly on. The fire will gently spark and flash for about an hour or so as the flash powder is dried and lit by the flames/heat throughout the fire.

Alternatively I have dipped both ends of q-tips into water and directly into flash powder before tossing them throughout the unlit fire.

The water will evaporate from the flash powder at varying rates for both of these methods and will produce a very exciting and eye-catching campfire.

Never enclose the flash powder in any casing - a build up of pressure at the point of ignition will result in an explosion. Be safe and play at your own risk!

I'm going to try this with old copper tubes if I can

Nice. Difference in flame color and melting may vary depending on penny year - pennies after 1982 only have 2.5% Cu whereas before this date they were 95% Cu.

I found that copper acetate crystals was really easy to make and could be tossed in the fire to get the same effects.... Probably not a good idea if you intend on eating off that fire after tho

The green flame kind of resembles the Northern Lights.
