Easy Colored Fire Project

It's easy to make your own green fire whirlwind or twister. This is a variation of the regular fire tornado project, except using a flame colorant to produce green fire.

Green Fire Whirlwind Materials

  • cylindrical mesh container (such as stapled chicken wire, screen or a metal mesh trashcan)
  • turntable or carousel (or even a rotating chair or stool)
  • methanol or other alcohol
  • boric acid, borax or copper sulfate

    Make the Green Fire Whirlwind

    1. Make sure the mesh cylinder fits on the turntable and freely rotates.
    2. Prepare a colorant fuel: Dissolve some boric acid in a small amount of methanol. If you don't have methanol, you can use borax or copper sulfate with rubbing alcohol.
    3. Place a fireproof container of the colorant fuel inside the mesh cylinder, which is on the turntable.
    4. Ignite the fuel and give the turntable a spin.
    5. The fire will go out on its own or you can blow it out.

    Safety Information

    Use reasonable precautions when performing fire projects. Do not perform this green fire project near flammable object. Have a means of extinguishing the fire, should an accident occur. While this project may be performed using solid fuel, the spinning surface may cause a solid to fly outward, presenting a hazard. The use of liquid fuel is advised. Methanol is toxic and may be absorbed through the skin, so if you use this chemical, avoid skin contact or inhalation of fumes.
