Firework or sparkler burns can have large effects on our hands' range of motion.

Fun family fireworks turn ballistic

The American Pyrotechnics Association estimates that over 10,000 injuries result each year from fireworks, close to three-quarters of which occur around the Fourth of July. This video shows just one rather explosive miscue.

In the early 1900s, Fourth of July celebrations were so dangerous that a reform movement emerged to make them safer.

Beyond burns, fireworks can harm respiratory, auditory, and visual health.

Fireworks contribute to air, water, and soil contamination and disrupt wildlife

Fireworks displays have far-reaching environmental consequences, including acid rain from displays during storms and microplastic pollution in water supplies. Wildlife has also been seen abandoning sites during fireworks and never returning.

Americans spent an estimated $14.8B for the Fourth of July 2025.

Fireworks usage on Independence Day comes from their celebratory use in ancient China

Burning bamboo stalks produces a small explosion that was believed to ward off evil spirits. As knowledge of fireworks, which initially used these stalks, carried over into other cultures, so did their use to promote good luck and celebration.

The US had about 155.4 million emergency room visits in 2022, and more than a third involved injuries, including poisonings.

Fireworks make a loud booming sound after explosion due to air expanding faster than the speed of sound.

Firework-related celebrations include an annual summer celebration in El Salvador, where residents throw kerosene-soaked balls to commemorate a 1658 volcanic eruption.

According to a survey by the National Retail Federation, Americans were expected to spend over $9B on food for Independence Day in 2026.

'Silent' fireworks have gained more interest in recent years as a quieter celebratory option.

One Chinese businessman controls 70% of the fireworks entering the US

A warehouse explosion in 2008 forced all pyrotechnic shipments to travel through the Shanghai port under three special permits Ding Yan Zhong was given. Since then, he has established a near-monopoly over the global fireworks distribution chain, with logistics and shipping hubs in China and California. (Some users may experience a paywall.)

'Silent' fireworks are not entirely noise-free

By using a reduced amount of flash powder—the ingredient responsible for the loud explosions that fireworks make—"silent" fireworks produce displays between 70 and 90 decibels, rather than the approximately 175 decibels heard in professional displays.

The most fireworks launched from a pyrotechnics suit is 642

Frenchman Laurent Nat, a pyrotechnics artist and performer with over 10 years of experience, set the world record on June 13, 2014. The suit, inspired by clothes worn by professional firefighters, is made out of 100% cotton and incorporates stilts to allow fireworks to be fired in all directions.

The deadliest fireworks accident in history was Marie-Antoinette's wedding

In 1770, a fireworks display in Paris celebrating the marriage of Marie-Antoinette to the Dauphin, later known as Louis XVI, resulted in as many as 3,000 deaths. Most casualties were caused by trampling from a panicked crowd of thousands rushing away after some fireworks were blown into the spectators.

The burning of different metal compounds, facilitated by combining fuel with oxidizers, results in explosions of varying colors. The timing and pattern are engineered through the arrangement of pellets and fuses.

Massachusetts is the only state that bans all nonprofessional fireworks.

Severe cases of food poisoning have doubled even as food recalls dropped

Food recalls were down in 2024 by 5% as compared to 2023. But some researchers suspect that’s just because there were fewer inspections or fewer people reporting illnesses: Hospitalizations from food poisoning more than doubled during that same period, from 230 to 487, and deaths rose from 8 to 19.

Pyrodrones combine fireworks with millisecond-accurate drone choreography

Drones are outfitted with fireworks and positioned using 3D software to ensure perfect timing and safe spacing during shows. A single GPS error during planning can ruin the show, as happened in 2024 when a drone crashed and injured a spectator due to programming failures.

Adding pellets of salt to gunpowder within a fireworks shell causes them to explode with different colors, but the type of gunpowder used also has an effect. Finely ground gunpowder burns quickly, producing streaks that swiftly burn out.

See Virginia's spike in HFMD cases in 2025

The state's own tracking showed a significant jump in HFMD cases in July 2025 as compared to the prior few years, and that more people were visiting the emergency room and urgent care centers for the disease, but epidemiologists could not explain why the numbers were so high.

Watch a drone flight through a fireworks display

This video explores the history, construction, and preparation of modern fireworks displays, including creating gunpowder from scratch. Experimentation with fireworks underwater is also featured, but they require special materials to prevent water from infiltrating the fireworks shell.

Visualize the components of fireworks

This article provides animated diagrams depicting how different parts of fireworks function. The elements work together through timed mechanisms to produce desired effects.

Variations in rapidly expanding gas and mechanical elements produce fireworks sounds

Chemical compounds designed to vibrate rapidly when ignited produce whistling, screeching sounds, while crackles and pops are created by small star pellets inside the firework, which explode one after another quickly. Fluttering and chirping sounds are produced by spinning elements that rotate rapidly as the firework ascends.

In 2024, US holiday retail sales reached $973B—nearly one-fifth of annual sales. Many companies depend on this season to bolster revenues.

China makes 90% of the world's fireworks, with Liuyang as its production capital

Fireworks were invented in China, but their predecessor, the firecracker, was discovered in Liuyang upon burning bamboo. Pyrotechnics have since become part of the city's culture. Liuyang has won many international fireworks display competitions.

In 2024, 332 million visitors to America's national parks spent an estimated $29B in local surrounding economies.

There were roughly 17 Black Friday-related deaths and 125 injuries between 2006 and 2021

A website called Black Friday Death Count or “BFDC” scrapes news headlines for Black Friday-related deaths and injuries reported around the world. It includes the overall count of Black-Friday related deaths, as well as the context for each of them.

Explore the chemical compounds found in fireworks

Besides the various salts and metals used to produce fireworks colors, shells are also filled with gunpowder and oxidizers to help fuel and accelerate reactions. Chlorates help strengthen colors, while dextrin, a starch, helps hold mixtures together.
