25 facts about fireworks

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 marvelous displays of science, imagination, pageantry, and, of course, history—a very long history, at that. While fireworks in America are most closely associated with Independence Day, 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 neighbor'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 Smithsonian Science Education Center. More than 2,000 years ago, around 200 B.C., 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 600 and 900 A.D., according to the American Pyrotechnics Association (APA). During that period, alchemists in China developed what would become black powder by mixing charcoal with potassium nitrate and sulfur. 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-fueled fireworks were now officially pyrotechnic events, they would likely not have satisfied the modern reveler. The Chinese didn't add colors 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.

The Chinese used fireworks in spiritual ceremonies

The Chinese originally used black powder fireworks not for entertainment, but for use in spiritual ceremonies. This was similar to their ancient predecessors, who used their air-filled bamboo fireworks to ward off evil spirits centuries before.

Aerial fireworks have military roots

It wasn't long before the concept of controlled explosions caught the eye of military tacticians, and by the year 1,200, the Chinese had invented rocket cannons. The devices used black powder to blast projectiles at approaching enemies. The deadly technology, however, also made it possible to blast fireworks into the sky—the aerial fireworks show was born.

Europeans adopted fireworks for entertainment

As the new military tech spread west, rocket cannons became artillery cannons and handheld muskets. Europeans adopted not just the weapons, but fireworks, as well. They began expanding the technology into elaborate displays that were held to celebrate religious holidays, military victories, and royal festivities—for the first time in history, fireworks were the life of the party.

Fireworks have always been part of July 4th since 1776

The Smithsonian printed excerpts of a letter Founding Father and future president John Adams wrote to his wife on July 2, 1776, two days before the signing of the Declaration of Independence. He wrote that he believed a massive celebration was in order and that the festivities should include fireworks, although he called them "illuminations." Adams got his fireworks and they've been closely associated with the holiday ever since.

Americans use tons of fireworks—literally

About 27.1 million pounds of display fireworks (small-scale explosives such as bottle rockets, firecrackers, and roman candles) were used in 2023, according to the APA. That, however, is just a drop in the bucket compared to the 246.5 million pounds of consumer fireworks that were used during the same time period. In total, 273.6 million pounds of fireworks were set off in 2023 alone.

Consumers used more fireworks as display use declined during the pandemic

The 273.6 million pounds of fireworks consumed in 2023 was a massive drop from the 461.7 million the year previously. In the summers of 2020-2022, during the COVID-19 pandemic, people took to setting off fireworks at home. During those three years, firework consumption toppled 400 million pounds for the first time ever. The use of display fireworks (professional-grade shows involving significantly more explosive material than consumer fireworks) dropped by more than half, from 64.1 million pounds in 2002 to 25.3 million pounds in 2022. Consumers, however, went from using just 126 million pounds to 436.4 million in the same span of time.

Fireworks are legal in most of America

Every state in America plus Washington D.C. permits some or all consumer fireworks that are legal at the federal level, according to the APA—all except one. Massachusetts bans all consumer fireworks, while Illinois, Ohio, and Vermont allow only novelty items like sparklers.

Fireworks are a billion-dollar business

According to the APA, "the U.S. fireworks industry has experienced unprecedented growth during the past decade and a half." In 2003, display and consumer fireworks revenue was $258 million and $517 million, respectively. By 2023, those numbers were $500 million and $2.2 billion. The organization traces the boom back to 9/11 and advances in fireworks technology at the turn of the millennium. 

An aerial shell contains six parts

The modern aerial fireworks shell is made up of six components. Each shell includes a lead fuse, stars or effects, supplemental burst, bursting charge, internal time fuse, and lifting charge—otherwise known as black powder—which is still made from the same elements originally mixed by the Chinese.

Two fireworks records were broken in 2019

Al Marjan Island in Ras Al Khaimah in the United Arab Emirates kicked off the start of 2019 with what might just be the greatest fireworks display in human history. According to Guinness, the show broke two records, one for the longest straight-line fireworks display, which extended for eight miles, and another for the longest chain of fireworks, which consisted of 11,284 shells. In 2020, a group in Steamboat Springs, Colorado, broke a record with a 2,797-pound shell that was deemed the largest in history—it was so huge that a giant mortar was built just to shoot it off.  

New York City hosts America's biggest fireworks display

The Macy's 4th of July Fireworks show is the biggest and most famous of its kind in the United States. In 2024, the pyrotechnics will launch from the Hudson River on a series of barges. The 25-minute show will involve more than 60,000 shells, with variations including cross rings, Saturn circles, crackling pistils, and a never-before-seen silver cascading burst with a kaleidoscopic center.

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. According to the Consumer Product Safety Commission (CPSC), 9,700 people were injured badly enough in fireworks accidents to require emergency treatment in 2023.

There are even some fatalities

Also in 2023, eight people died in fireworks-related incidents, according to the CPSC. Of those, five people were killed by fireworks misuse, two deaths were due to fireworks misfire/malfunction, and one died via unknown circumstances. The CPSC stresses in its report that the number of deaths listed is a conservative estimate and the actual number of people killed by fireworks in 2023 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 National Fire Protection Association, they burn incredibly hot—around 1,200 degrees—hot enough to melt glass. 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

About two out of every five fireworks injuries are due to burns, and a huge plurality—about one in three—of all fireworks injuries are to the hands and fingers, according to the CPSC. The head, face, and ears are the next most likely injuries.

Men suffer most of the injuries

Men account for the majority of fireworks-related injuries. According to the CPSC, injuries are split 67/33 between men and women.

Young people are especially susceptible

People younger than 24 years old account for 60% of the fireworks injuries that are serious enough for emergency-room treatment, according to the CPSC. Young people between the ages of 15 and 24 were the biggest risk group, making up 28% of emergency room injuries. 

Teens between 15 and 19 are most likely to be injured

At 4.5 injuries per 100,000 people in 2023, 15 to 19 year olds had the highest rate of firework injuries treated in emergency rooms, according to the CPSC. Kids aged 5 to 9 had the second-highest estimated rate (4.0 injuries per 100,000 people).

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 ATF states: "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 2022, fireworks were the cause of 31,302 fires, according to the National Fire Protection Association, including about 26,500 outside fires, 3,500 structure fires, and 900 vehicle fires. Those fires killed an average of six people, caused 44 civilian injuries, and did $109 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. 

Fireworks laws are getting looser

At least nine states have made their laws more permissive since 2000, according to the APA, with many opting to legalize handheld and ground-based sparkling devices. Another eight states liberalized existing laws since 2011.

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 3.4% of all common outdoor summer activities for children between the ages of 5 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 basketball.
