Thank you for coming in, dear Philip.
I see that you also sugest i should fire the things with blanks; in this case when the procession comes by, risking to burn the priest's cassock

.
However, i can't help looking at this type of things without attributing them a more bellicose utility.
I have heard versions (i ignore if documented), where they could make a lot of damage, even not loaded with a classic projectile. Like being used in series, to burst strategical spots; or fired under flagstones, or embedded in castle gates, anywhere imagination goes.
Talking of imagination, firing sausages is not a bad number

.
Concerning fireworks over here, we lately hear intense campaings stimulating the end of their use, mainly for safety reasons; every seasons countless accidents occur in the country, with the use (or misuse) of fireworks. I have seen in the TV a little village where they play a record with the noise of fire crackers in the curch tower, to substitute the real thing and possible accidents. How's that?
Best.
Fernando.
