Spark rifle

 For when you want sparks to hit something.

At its crudest, this is a sparkcone shoved into a rifle barrel. But BUNGCO was dissatisfied. We are sportsmen and sportswomen here, and we wanted rifles that will shoot one spark at a time. What is a spark but a fragment of incadescent metal, anyway? We had plenty of those. This is not a tracer bullet, but a pyrotechnic sparkler-type of spark.

The spark rifle would be used to shoot condoms inflated with helium, to prevent their escape into the stratosphere. At the BUNGCO annual gala, a bubble machine akin to that used by Lawrence Welk will blow oxyacetylene bubbles, which will then be summarily dealt with by a corps of sharpshooters using spark rifles.

Also available in Roman Candle.

       How does this work? Do you think you could magnetically accelerate a piece of burning magnesium? Air rifle thermite pellets witha little oil to diesel and ignite?

       I am not sure how those spark cones work. Those sparks shoot pretty high but I am not sure what propels them. I could not find that on the web. Roman candles would be easier - just ignite that little chunk of stuff and fire it with a CO2 charge like a pellet gun.   

       I think if you used a railgun to accelerate a steel splinter it would effectively become a spark due to ohmic heating.

       That's what I'd like to see, a tiny tiny railgun or something that could use the heat to expand gas to push a burning cinder down a barrel.   

       I think the easiest is an airgun that has a spark gap at a point in the barrel to ignite a burning pellet. I want something that will spark at will.

       [QED] will magnesium grains work in a railgun ?

       Glowing yellow steel is not magnetic. Above some temperature that is probably influenced by carbon content, say 750°C for argument's sake, it is in the austenite phase, rather than ferrite. Austenite is not magnetic.
