This looks breathtaking. I just want to know is it COMPLETELY impromptu or does it involve a gimmick. Gimmick do sometimes create bigger effects...but I'm tired of gimmicks and I read Justin Miller saying it was impromptu. Is the can borrowed and its "technique?" Or do you have to "tweak" it first? Without exposing anything I would love some feedback. It looks worthy of purchase....but so did downfall. Thanks guys!
