Behind all the eagerness of fireworks, chemistry plays an importantrole in creating the v ivid colours we witness starting up the sky. Theactual chemical reactions that move back place in the explosions requirethe use of oxidisers, reduction performers and binders. The add onitions ofvarying metal chlorides add the colours.
