It’s easy to make colored fire. One of the brightest and most colorful examples of colored fire is green fire. See how to use household chemicals to make green fire yourself.
Transcript: Green Fire Chemistry Experiment
Hi, I’m Dr. Anne Helmenstine for About.com. Today I’m going to show you how to do one of my favorite chemistry projects, making green fire.
Green Fire Materials
It is extremely simple to make green fire. All you need is boric acid, which is sold in the pharmacy section of many stores, and methanol or methyl alcohol, which is most easily found as a fuel treatment with automotive supplies.
Start the Green Fire
Pour a little boric acid into a fire-safe container. Add a small amount of methanol, being careful to avoid spilling any on your hands. Light the fire!
How Green Fire Works
The green color comes from heating the boron in the boric acid. Many metal salts burn in characteristic colors like this, though the green fire is probably the easiest to try yourself.
I hope you’ve enjoyed this project. You can find more chemistry projects if you visit me online at About.com. Thanks for watching.
Caution:Adult supervision required.
