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.
Step 1: Materials and Tools
Electric matches are surprisingly easy to make, all you need is thin wire, a match, and some electricity.
When you research electrical matches, they will tell you that you need special nichrome wire, designed to heat up quickly., when really all you need is something thin. The more electricity you have available, the thicker the wire you can get away with.
The wire I used was a single strand from some multi-core electrical wire, the sort of stuff you buy for home electronics. I stripped it, and pulled out individual strands a few centimetres long.
You will also need tape - cheap stuff is fine, and it's better if it is clear, so can check your wiring before using the match.
Tools-wise, just use whatever you are comfortable with for cutting and stripping wire.
