hello mrShantanu, this a late reply coz im a newcomer here. thats a good and bad idea, I think it could be used as an eye of an arrow that released it by its bow. the fully charged capacitor (exp: 2200mf50v more) put on the end of arrow with its end of two electrodes arranged closed as possible, so when it throw and touch on a critical flammable area or explosive material and electrode shorted and fire or explode will happen.
