And by "exploding", I mean something that gives a good visual when hit, not an incendiary device. What gives a good visual when hit from long range? I know that a shaken can of cheap soda gives the effect that I'm looking for at close range, but what about a 2 liter bottle? From a long range the effect of shaking it would go away by the time the shot was placed but would it still blow? Has anyone tried baby powder or corn starch in a ballon? Any other ideas?
