In China, it is a tradition to celebrate important events with fireworks.Especially, on New Year’s Eve, people like to set off fireworks at 00:00 to welcome the coming year.Fireworks are fun and beautiful to look at.However, on the other morning,piles of tattered packages of fireworks are left over on the road. Moreover, the air quality is always terrible, because of toxic heavy metal particles and dusts that remain in the air .

This work aims to make an environmental friendly firework which does not need mining rare minerals from the earth nor produce harmful combustion products.
