The Chinese accidently invented fireworks when some alchemists were trying to make an immortality potion, but failed. They didn't fail all to badly though because they had invented one of the most recognised features on special days of the year like Chinese New Year or New Years Eve. Everybody looks forward to having fireworks go off at big parties like New Years Eve. The Chinese were really good at making great parties and festivals. they would set off fireworks, tell stories and dance all night. Parties nowadays aren't all that different today. Some people even call New Years Eve the highlight of their year and it's all thanks to an alchemist in ancient China who thought that he stuffed up.
