Summer
Sparklers have an introduction, development, climax and conclusion. It's said that it's representative of humans and their lifetimes. Firstly the "Peony", constantly burning through oxygen, it gets bigger and bigger rapidly, kind of like youth. Next a "Pine Needle", they give off such violent sparks but are still one of the most beautiful things I've ever seen. After that a "Willow", where the sparks eventually die down to the final, most quiet spark of all. Finally like a "Chrysanthemum", they are united and yet at the same time, they are scattered.
