Bon Dieu!! Shooting something- or someone with that would be tantamount to an atomisation process. Mind you, for a human, it would save on the bodybag. You'd just need a few dabs from napkins to clear up afterwards!. Given your apparent experience at shooting rads/blocks out, though, I'd guess that you were once in the 50? Or, perhaps, someone hiding behind a bush, trying to drum up business for a local repair shop
A sort of radiator 'hitman', gun- for- hire.In fact, I've heard of cases here windscreens (translation: 'windshields) being damaged with air rifles when trade is slack...so this not without precedent.
Interestingly, the theme tune to Hawaii 50 is used in a comedy series here ("One foot in the grave', starring an embittered, septic..and very funny old scot). Every time he goes to the toilet for a potentially noisy number '2', he plays the '50' tune to disguise the ensuing eructations, and gaseous outbreaks. To annoy my ex, and demonstrate my unrelenting immaturity, I used to keep a gas mask on the outside of the toilet door(translation: 'bathroom door'); and would also hum said Hawaii 50 theme loudly...
