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

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.

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 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.

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.

In 1906, the city banned fireworks displays, forcing the Times Square celebration to find a new centerpiece. The Times commissioned Jacob Starr, a Ukrainian immigrant who worked for Strauss Signs, to develop an ornament. He returned with the now-iconic New Year’s ball.

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.

Professional pyrotechnician Patrick Cyrana answers the internet’s most curious questions about fireworks, from designing ghost effects and exploring how electronic firing systems work to explaining what it takes to create displays in the rain.

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.

In 2019, Chinese-American gangster Xizhi Li was arrested for an expansive money laundering scheme spanning four continents. Li reportedly laundered hundreds of millions of dollars for cartel members, wealthy Chinese Americans, and other foreign countries.

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.

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.

Many countries have attempted to ban firecrackers, though some rolled back those restrictions for the sake of the holiday. This tradition, along with numerous other practices, has evolved for decades since the origin of the festival.

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.

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.

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

The app's ownership is now majority American, though TikTok CEO Shou Chew, who is Chinese, remains on the board of directors. It's unclear what, if anything, has changed for American users, as the company has historically kept the specifics of its algorithm a secret.

In 2018, China stopped accepting most of the world's recyclables. This highlighted how dependent the US recycling system was on a single foreign buyer and forced cities to landfill materials they had once diverted.

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.

China's vast, state-owned tobacco market has produced enough regional brands and packaging variants to sustain a dedicated collector community. Ciggies.app functions as both a product database and an enthusiast social network, with entries spanning current mainland releases, historical discontinued brands, and international imports.

Unlike other countries that primarily use profits from natural resources, China's sovereign wealth funds are fueled by the country's mounting trade surplus. Among the two largest are the State Administration of Foreign Exchange (SAFE) fund and the Chinese Investment Corporation (CIC). China also operates the Silk Road Fund, a strategic investment initiative that backs infrastructure creation in developing countries.

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.

The "Silicon Valley of Hardware" is a major manufacturing hub. This WIRED documentary from 2016 does a deep dive into how this Chinese city's practice of copycat manufacturing alongside its innovative culture has made it China's own Silicon Valley.

In 1987, he started shipping VHS tapes of games to state-run TV stations in China, and opened an NBA office there by 1992. Today, China is the league’s second-largest market.

Copper chloride emits blue light when heated, but breaks down at the temperatures created when fireworks explode. Pyrotechnicians continue to search for an ideal mixture that provides a temperature high enough for copper chloride to shine brightly without being destroyed.

The Ruggieri family transformed fireworks from military to theatrical displays by focusing on artistry. Claude Ruggieri's knowledge of chemistry allowed him to produce vivid green fireworks, a first in Europe.

Recent data from the Federal Reserve shows that the richest people in America own 93% of all the country's stock—the highest level ever recorded. Meanwhile, the bottom 50% of Americans held just 1% of all stocks.

In 2022, China had a fifth of the world's population and bought nearly half of the world's cigarettes. This investigation explores how China became plagued by tobacco consumption, something epidemiologists say will strain the country's health system...

That's more than any other country in the world. Most of the flowers Americans purchase are imported, creating an economy that's both booming and reliant on dwindling natural resources.

In 2024, after Polymarket markets favored what turned out to be the winning outcome of the US presidential election, agents raided Coplan's New York City apartment. Coplan, who was only 26 years old at the time, was home during the raid and turned over his devices to authorities.

Taiwan is a leader in the production of semiconductors. In the event of a Chinese invasion, what happens if China controls the supply chain for these indispensable materials? How would it affect the United States as well as other nations already dealing with disruptions due to Russia's invasion of Ukraine? This blog explores these questions and more.

As of 2023, the company has 40% of the electric vehicle market in China and produces more than 3 million EVs for customers worldwide. Its vertical integration, which includes building its own batteries and cargo ships, has allowed BYD to lower retail costs.
