I have written pieces about fireworks in this space for several years now. This year is no different, but instead of describing how modern fireworks operate, we shall, courtesy of The Doctor, take the TARDIS back to 1784, the first Independence Day after ratification of the Treaty of Paris, so for the first time the United States was a truly independent Nation on 04 July.
Unfortunately, my video camera was not working at the time, so I shall have just to describe what fireworks looked like at the time. The Doctor told me that he would come again and that we would go to the 1785 one for next year, and make sure that I had a functional video camera.
Except for color, fireworks in that era were similar to some of the least advanced ones that we have today. The complex aerial effects are quite modern, bright color is modern, and set pieces are also modern.
