I want to take a photograph of the blue bolt that jumps from the finger when touching a grounded metal object. I began attempting this last night and realized how difficult of a task it was.

I've searched the internet and found no evidence of someone successfully taking a photograph like this before.

Any suggestions or words of advice? I started off trying 2 and 5 second exposures in a dark room, and shocking a vent while the camera is pointed at it from the side. The camera was on a tripod of course.

All I have gotten so far is a blue blur. Please, feel welcome to try it yourself :)
