It is generally agreed that the Chinese invented fireworks shortly after inventing gunpowder more than a thousand years ago. Today, the majority of fireworks come from China, although a surprising number of manufacturers are located in the US.</p><p>It is also surprising how much engineering and technology goes into creating a commercial fireworks display. So this Independence Day, as you and your family enjoy the spectacle of aerial explosions and starbursts, give a moment’s thought to the engineers and technicians who make it all possible.</p><p>Here are some interesting technical tidbits to help you understand the science behind the boom.</p><p><em>Senior Editor Kevin Clemens has been writing about energy, automotive, and transportation topics for more than 30 years.
