You have seen my lightpainting photos, created with steelwool and fire. If not, check out my photos at VeeR. This is how it looks as a video. If you see it the first time I bet you are astonished that the photos has been created from this. This kind of photography is called lightpainting with steelwool and the sparks are tiny glowing parts of steel. As you can see, they can cause a fire really quickly.
