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.
