One of my sons tells a story about flying in a window seat from Texas to the Midwest one July 4th night a few years ago and seeing fireworks all over the sky during the entire flight. He said his view was so entertaining that the two hour flight felt like it was over very quickly.

China produces and exports more fireworks than any other country in the world and it is also believed to be the country where fireworks originated. As early as 200 B.C. the Chinese would roast bamboo and when it got hot enough it would explode because of all of the air pockets. This was thought to ward off evil spirits and ghosts but evolved into a means of scaring off enemies as well.

At some point between 600 and 900 A.D., the Chinese began mixing together potassium nitrate, (a common kitchen seasoning at the time) charcoal, sulfur and other ingredients into an early form of gunpowder. The Chinese would stuff bamboo shoots with the homemade gunpowder and then throw them into the fire to produce a loud bang. These were the first fireworks and were used to celebrate special events.

Next Tuesday, we will mark 241 years since the Second Continental Congress approved the final version of our Declaration of Independence from English rule on July 4th, 1776. The first Independence Day celebration was held the next year in Philadelphia on July 4, 1777 with fireworks to raise the spirit of our new nation since the Revolutionary War was still going on.

That first American fireworks display was crude by today’s elaborate standards, but it got the job done. There were some rockets shot into the sky, but most of the first fireworks displays were of patriotic images arranged and lit up on raised platforms for the crowds to see.
