I love fireworks, folks. I don't see the spectacle often, but when I do , it is an absolute beauty to behold, especially when it is an entire choreography. I sometimes cannot believe that there are people whose job it is to "make" fireworks. Especially, the development of new ones must be a blast!... in more ways than one :-P. This episode looks at how fireworks create colour at the sky. I hope you enjoy it. I can now be reached on twitter under @ChemistryinEve1 , if you have feedback that you would like to share.
