Actually, some old dynamite that is leaking an oily liquid is a sure-fire way to get a flash. Just don't drop it.

Group, I haven't been following this thread that won't die, but I've contributed to others :^) If the problem is that it is expensive to detect when a bullet hits a target half a mile away, then have I got a solution for you! Visit any friendly neighborhood terrorist supply store and buy a small quantity of PETN, or any other explosive that can be detonated by the impact of a bullet. Smear a coating of this over the area of the target that you intend to hit. When you hit the target, there will be a very bright flash with a very fast propagation velocity, which should be adequate for the average 10X scope and photosensor. No, I don't know where to find a terrorist supply store. Perhaps you can make do with the PETN in blasting caps, or brew up a batch of nitrogen tri-iodide, as any college freshman could do in the fifties. Or try the powders from a Very pistol flare. Yours for more creative solutions, Bill Hawkins _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
