Caution: This project is all about fire. Make the proper precautions to keep your fire from spreading. If you are in an area experiencing drought, you shouldn’t be making fires at all. Contact your local fire department for help with controlled fire experiments.
Fire, on its own, can be beautiful. It is beautiful, intangible, and seemingly alive. When we can add a bit of control to that fire, it becomes mesmerizing and entrancing. I’m going to show you how to harness this beautiful and dangerous phenomenon called a fire tornado on your own.
To build the tiny fire tornado, you’ll need the following:
- A “lazy susan” of some kind to spin everything
- Wire mesh trash can
- Denatured alcohol
- Cotton swabs
- Small fire proof container
Place cotton swabs in your small container and add some denatured alcohol. The cotton swabs keep the alcohol from splashing out as you rotate everything. This container goes inside your wire mesh trash can, which is sitting on top of the lazy susan.
Once you light the alcohol on fire, give the assembly a gentle spin. In a moment you’ll see your flame climb upwards in a beautiful little fire tornado.
- Turn the whole thing very slowly and gently. It does not need to go fast to make the tornado.
- Make sure your fire is as close to the center as possible. Having it off center will cause the fire tornado to fail.
Safety Note: Suffocate this flame with something that fits over your fire container. Do not blow this out or pour water on it.
To go big, you’ll need the following:
- 12 box fans
- A metal container for the fire
- Denatured alcohol
Building the big fire is pretty easy. Place your box fans in a circle around a metal container. Slightly angle them all in the same direction so that they are not facing directly toward the fire. Light your fire and turn on your fans. Go around your circle and adjust the fans as necessary.
- Turning the fans on too strong of a setting can kill the fire tornado. Try weaker settings first.
- The angle of the fans should be barely off center. Turning them too far will kill the fire tornado.
Safety Note: do not throw anything into the fire container. Your fuel will splash out and spread fire. A damp piece of plywood can be used to suffocate this flame if needed. The entire metal container and contents will be extremely hot. Let it sit and cool before anyone touches it.
