it's like fireworks, dad. you said the colors and patterns come from all the minerals. their making a mutual arrangement designed to ignite and illuminate.
you said the designers crafted this one boomy blue and that one sparkly-white. this cascade brilliant, that smiley face a dud.
flying high or bursting low, it's all in the timing and atmospheric conditions. don't forget chemistry and physics. human ingenuity (and error). some are dampened or damaged in transit.
do you think they know it's all ashes at the end? maybe. probably. but what a ride. what a show. I don't care if the music is synchronized. ooh. ahh.
