Making blue fire is an easy DIY project, and there's more than one way to do it. Here are a couple of pointers for making it yourself.

Natural Blue Fire

The easiest way to make blue fire is to burn a chemical that naturally produces a blue flame. Most types of alcohol burn as blue fire; these include: 

  • Ethanol (e.g., rum, vodka)
  • Methanol (wood alcohol, Heet fuel treatment)
  • Isopropyl alcohol (rubbing alcohol)
  • Natural gas also burns with a blue flame

Easy Method of Making Blue Fire

Several metal salts burn with a blue flame, such as certain copper, arsenic, and lead compounds. Antimony and lead are toxic, but you can use copper(I) chloride to produce blue fire by following these instructions:

  1. Add a small amount of water to copper(I) chloride to dissolve the salt. If you cannot find copper(I) chloride, it is possible to make this chemical yourself. Copper(II) chloride is more widely available, but it will burn with a blue-green flame.
  2. Soak a flammable material with the copper chloride solution. Good choices include sawdust or pine cones.
  3. Allow the material to dry.
  4. When you light it or add it to a normal fire you will get blue fire.
