What I used was a Grade 000 steel wool for the best ignition, a steel whisk tied to the end of a dog leash to spin the wool around. 

 

To set up, I went to a dark, dry area and made sure that my model didn’t move as well as put my camera on a tripod.  I put my camera into manual mode using a longer exposure of about 10-30 seconds. 

 

I first lit up my subject with a flashlight. I did this 3 times, once with a regular flashlight, and then twice I put a coloured gel in front of the flashlight. I lit up my subject out of view from the camera to ensure no streaks ended up in my photos.

 

After lighting my subject, I stood behind my subject with my steel wool in the whisk tied to the dog leash. Ignited the steel wool and spun the whisk around.
