It's hard to imagine there's a person in America who doesn't have at least a few childhood memories associated with fireworks.
Thunderously loud, dazzlingly bright, and of course, that grand finale that never seems to end—fireworks are a nearly universal symbol of celebration across the world.
They explode when wars are won, during holidays, and even when Disneyland closes down for the night. Millions of people line up to see them, and millions of dollars are spent buying them.
Those consumers, however, should keep in mind that fireworks make celebrations better only when they're handled safely—nothing kills a party faster than a trip to the emergency room for injuries involving exploding projectiles.
Powerful and potentially very dangerous, fireworks are nothing to trifle with. Statistics show that thousands of Americans, many of whom are children, are injured each year by preventable accidents with fireworks.
When they are done right, however, today's best fireworks shows are truly marvellous displays of science, imagination, pageantry, and, of course, history—a very long history, at that. They trace their roots back to well before July 4, 1776. The story of fireworks starts thousands of years ago and involves dramatic changes in military conquest, spirituality, and good old-fashioned fun.
From a handful of bottle rockets whizzing up and popping over the neighbour's yard to highly coordinated televised events that light up entire major cities, summer is fireworks season.
Here's a look at how it all started, how it evolved, the numbers behind the industry, and the realities of how high the stakes are when you decide to run your own pyrotechnics show.
Keep reading for a peek into the 2,000-year journey of the greatest party novelty in the history of the world.

The first fireworks weren't really fireworks
The original fireworks were actually just sticks of bamboo, according to the . More than 2,000 years ago, around 200 BC., people in China threw bamboo into fires, which would make the hollow rods explode when air trapped in pockets inside would burst after being heated.

Real fireworks emerged in China between the 7th and 10th centuries
The planet got a whole lot noisier somewhere between AD 600 and 900, During that period, alchemists in China developed what would become black powder by mixing charcoal with potassium nitrate and sulphur. The accidental discovery was the precursor to modern gunpowder and the ingredient that makes fireworks go boom.

The original fireworks shows were pretty lousy
Although powder-fuelled fireworks were now officially pyrotechnic events, they would likely not have satisfied the modern reveller. The Chinese and they had not yet developed projectile explosives, so fireworks shows didn't light up the sky—or anything, really. They simply tossed the mixture encased in bamboo or paper into fires, where it ignited and made a series of pops, like modern firecracker strings.

Aerial fireworks have military roots

Consumers are using more fireworks as display use declines
The 404.5 million pounds of in 2020 was more than 1 million greater than the year previously—in the summer of 2020 America was on lockdown, and people took to setting off fireworks earlier and more frequently.
That 404.5 million pounds is approaching triple the 152.2 million pounds consumed in 2000. The use of display fireworks (professional-grade shows involving significantly more explosive material than consumer fireworks) dropped by more than half during that time from 50.6 million pounds in 2000 to 18.7 million pounds in 2020. Consumers, however, went from using just 102 million pounds to 385.8 million pounds in the same span of time.

Fireworks injure thousands every year
Fireworks are, for what should be obvious reasons, potentially very dangerous devices that explode, burn hot, and travel at high rates of speed. (CPSC), 10,000 people were injured badly enough in fireworks accidents to require emergency treatment in 2019.

There are even some fatalities
Also in 2019, in fireworks-related incidents. Including those 12 deaths, CPSC calculates the average death toll from fireworks to be 7.9 deaths per year. Of the 12 who died the most recent year, seven were killed by "misuse of fireworks," two deaths "were associated with fireworks device malfunction (late ignition)," and three were killed via "unknown circumstances."
The CPSC stresses in its report that the deaths listed is a conservative list and the actual number of people killed by fireworks in 2019 is likely higher.

Sparklers are not safe toys for children
Sparklers are often viewed as benign and safe alternatives to fireworks that are okay for kids because they sparkle and glow, but don't explode. According to the , they burn incredibly hot—around 2,000 degrees—hot enough to melt metal. Many children suffer severe burns by dropping sparklers on their feet or after sparklers ignite their clothing with incredible speed.

Most injuries are to the extremities
More than half of all fireworks injuries are due to burns, and a huge plurality—nearly one in three—of all fireworks injuries are to the hands and fingers, . The head, face, ears, and eyes are the next most likely injuries.

Cherry bombs and M-80s are illegal, dangerous, and common
Cherry bombs, M-80s, silver salutes, M-250s, and quarter sticks are classified as illegal explosives that are banned by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF).
They are, however, illegally manufactured and distributed en masse every Fourth of July. "The explosive compositions in these devices are typically extremely sensitive to heat, shock, electrostatic discharge and friction that may initiate, unexpectedly causing serious injury or death. The risks associated with these devices are further compounded because the persons manufacturing, transporting and using these devices often do not have the knowledge, skills, and experience required for such activities."

Fireworks start thousands of fires
In 2018, fireworks provided the spark for 19,000 fire, , including 17,100 outside fires, 1,900 structure fires, and 500 vehicle fires. Those fires killed an average of five people, caused 46 civilian injuries, and do $105 million worth of damage. More fires are reported on July 4 than any other day of the year. Given dry conditions and increasingly damaging wildfires, fireworks should not be used in places that can easily ignite.

In the big scheme of things, fireworks injuries are fairly rare
Fireworks are black powder explosives and therefore are, of course, dangerous. That said, it is certainly possible to transport, store, and use fireworks in a safe, responsible manner—actually, fireworks account for just 2.4% of for children between the ages of five and 18. In fact, well over half of all such injuries can be traced to just three activities, none of which involve explosives: swimming, bicycling, and playing in playgrounds.
