I recently had a need to "magically" light a bonfire at a Cub event. Other recent campfires had been dramatic, but obvious in their mechanism (burning things sliding down a wire or people pushing flaming brands into the fire). I wanted something more subtle, that the Cubs wouldn't notice happening. Something I could do from a distance.
So, I turned to the electric match.
As I describe here, the electric match is quite versatile - as well as lighting campfires, you can use it to precisely trigger pyrotechnics, stage effects or model rockets.
Please be aware, though, of your local laws - in the UK, home-made pyrotechnics, solid rocket fuel or explosive mixtures are absolutely banned without special licenses.
