Two years ago I uploaded a video showing how I make fireworks using steel wool and a length of wire. I had a great opportunity to film under a nice sunset and decided it was about time I filmed these fireworks again, with a little bit of an updated method. Here is my previous video for anyone interested in seeing more: http://youtu.be/wdbCzYN95cg
A note based on a question or two asked: These fireworks are very environmentally friendly. The only significant byproduct is rust, which is a common natural mineral all over the world, and is quite healthy for aquatic ecosystems.
There is clearly a fire hazard when using steel wool in this way so I am always very careful not to attempt this in dry environments.
