Pyrotechnic fun with a hunk of steel wool and a wire

Steel Wool Sparks
As any junior high school student knows, steel wool burns. These guys took this demonstration to a new level by attaching a piece of steel wool to a wire, lighting it, and swinging it around wildly. Very pretty!

Reader comment: David says:

The same effect can be sustained for longer by attaching a chicken wire cage to a chain, filling it with wire wool and dipping it in paraffin. This is known by the much less macho name of "sparkle poi", and typically throws sparks about 30ft in every direction.
