Halloween: How To Make a Green Flame Jack O' Lantern

This is the green flame jack o' lantern made by a high school chemistry teacher. It presumably distracted students long enough to look up from their phones for a second, then back at their phones to take a picture. Want to make your own? We're in luck! Well, I'm completely out of luck, but at least we have instructions for how to make green fire. My apartment building is going to look so cool burning to the f***ing ground!

Green Fire Materials


Boric Acid - Medical grade boric acid can be found in the pharmacy sections of some stores for use as a disinfectant. It is a white powder. It's not the same chemical as borax. I used Enoz Roach Away™, which is 99% boric acid, sold with household insecticides.
Heet™ Gas Line Antifreeze and Water Remover - Heet™ is sold with automotive chemicals.
Metal or Stoneware Container
Lighter

Instructions for Making Green Fire

Pour some Heet™ into the container. How much you use will determine how long your fire will burn. I used about a half cup of Heet™ for approximately 10 minutes of fire.

Sprinkle some boric acid into the liquid and swirl it around to mix it up. I used 1-2 teaspoons of powder. It won't all dissolve, so don't worry about some powder at the bottom of the container.

Set the container on a heat-safe surface and ignite it with a lighter.

Apparently the instructions above are for outdoor use only and probably not for use in a jack o' lantern. I doubt a jack o' lantern could sustain such bitchin' flames for very long. Still, don't let that stop you from experimenting. Experimenting is the mother of invention. "No. Necessity -- necessity is the mother of invention." Oh right, like you're friends with Invention and know her whole family.

Thanks to BrianA, whose jack o' lanterns burn with the fire of hell because he managed to kick a hot coal out of the devil's ass one time.

    How about Copper Sulfate crystals? How would they work?

  • Michael Knight

    weird to not just use copper wire or shavings as they too will emit a green tint to flame.
    don't breath the smoke though.... might need to have a hotter flame too...
    i've thrown copper scrap on a bonfire many times to get a cool blue green flame....

    Did you just suggest to people they put fucking Boric acid in their jackolanterns? The jackolanterns that kids play with all the time on Halloween? You're aware boric acid is fucking toxic right? Here come the lawsuits.

  • Tommy John

    Boric acid has low toxicity if eaten or contacting skin. I think the more pressing problem would be a child eating something that is on fire.

  • Paul Atreides

    That's because your an imbecile. Kids touch Halloween decorations, they knock over a jack o lantern spilling out boric acid which they get all over their hands then they eat candy. Do I have to draw you a fucking picture? Enjoy the lawsuits and dead kids.

  • TwiZtedS

    Why is a lawsuit the first thing that comes to your mind? Can't anyone anymore take responsibility for their own actions without blaming their ignorance on other people and expect a payout for it?

  • MustacheHam

    This is true. I mean what kind of responsible parent would let their kid go near fire? It would indeed be their fault.

    Anyway...It would be best to keep the fiery gourd closely guarded and away from tiny hands so reckless actions don't take place.

  • Michael Knight

    for the children's sake, the pumpkin should be placed on a table in the middle of your living room easily visible through your front window.

    Heet is just isopropyl alcohol. You can also buy it at a pharmacy, also used as disenfectant.
