Since time immemorial, conflict and the urgent necessities of war have driven rapid innovation. Many everyday products trace their origins back to military needs. From wristwatches to instant coffee, items that once kept soldiers alive, efficient, or comfortable now fill our kitchens, closets, and offices. Here are 10 objects with surprisingly martial origins.

Now a ubiquitous fabric present in everything from clothes to carpets, nylon debuted in WWII as a replacement for scarce silk in parachutes, ropes, and tire cords.

Its lightweight durability made it indispensable for military supplies. After the war, nylon quickly transitioned into civilian life, with stockings becoming its first big hit.

First patented in the late 19th century, zippers gained traction during WWI as fasteners for military uniforms and gear. Buttons proved slower and less reliable under battlefield conditions, making zippers a more efficient choice.

The military’s adoption helped standardize their use, and after the war, zippers spread rapidly into civilian clothing, luggage, and countless household items.

In 1795, Napoleon offered a prize for a food preservation method that could feed his armies on long marches without risk of spoilage.

Nicolas Appert, a French confectioner, spent 15 years experimenting before developing a process of sealing food in glass jars and heating them to sterilize the contents. Appert received the prize in 1810, and before long, the technique was adapted to tin cans, which soon found their way into military rations.

A precursor to modern instant coffee appeared during the American Civil War as a concentrated coffee, milk, and sugar mixture called Essence of Coffee. Soldiers mixed a teaspoon with hot water, but many complained it had the consistency of axle grease (yikes!).

In the decades that followed, the concept was refined, and by WWI and WWII, the U.S. military was mass-issuing instant coffee to troops for convenience and morale. Civilian popularity grew alongside military adoption.

During WWI, officers found pocket watches impractical during fast-paced and unpredictable combat conditions. Many soldiers began strapping them to their wrists for quick time checks, turning a personal improvisation into a battlefield necessity.

The first true wristwatches were designed specifically for this purpose, and the term "trench watch" soon became common. Surprisingly, these early designs already featured enduring innovations, such as luminous dials for nighttime visibility.

When the U.S. entered WWII, the Army invited more than 130 companies to develop prototypes for a lightweight, four-wheel-drive reconnaissance vehicle; only Bantam and Willys-Overland responded. The resulting Willys MB "Jeep" proved rugged, versatile, and indispensable to soldiers.

After the war, surplus Jeeps hit civilian markets, sparking the off-road craze and laying the groundwork for modern SUVs.

Instant noodles were inspired by post-WWII food shortages in Japan. Momofuku Ando, founder of Nissin Foods, invented them in 1958 as a quick, affordable, and portable meal, ideal for a country struggling with limited food supplies.

The noodles were flash-fried to remove moisture, making them lightweight and long-lasting. The concept was influenced by military-style rations, designed for easy storage and preparation.

Zippo lighters were standard issue for U.S. troops in WWII and Vietnam, valued for their windproof flame and reliability in harsh conditions. Throughout the conflicts, the company devoted its full production capacity to meeting military demand.

Afterward, the iconic design and dependability spoke for themselves, turning Zippos into a pop culture symbol of ruggedness among civilians.

Specially designed in the 1930s for British paratroopers, cargo pants featured extra pockets for maps, ammunition, and essential supplies, allowing soldiers to carry gear hands-free during airborne operations.

The practical design proved so effective that it was widely adopted by other Allied forces throughout WWII. After the war, the durable pants transitioned into civilian life as reliable workwear for laborers, hikers, and adventurers.

While freeze-drying, or lyophilization, has been known for centuries—the Inca were freeze-drying potatoes as early as the 13th century—it wasn’t until WWII that a commercially viable process was developed.

The military needed a way to preserve blood plasma and penicillin for soldiers in harsh battlefield conditions, where refrigeration was a rare luxury. This demand drove the development of modern freeze-drying techniques, which are still used today for food, medicine, and scientific materials.

10 lost treasures around the world humanity still hopes to find

If you were asked about your most priceless possession, what’s the first thing that pops into mind? And what would you do to protect it? Since time immemorial, pirates and princes, captains and mysterious men have acquired wealth and done the impossible to defend it. So much so that from treasure chests to gold-filled trains, some riches were hidden so well that they have vanished to this day. Let’s find out about 10 of the most unbelievable lost treasures around the world and try to imagine what we’d do if we found them.

The Amber Room, often called "The Eighth Wonder of the World", was an 18th-century opulent chamber made of six amber panels, gold leaf, and mirrors. It was commissioned in 1701 for Prussia’s King Frederick, and later gifted to Russia’s Tsar Peter the Great in 1716.

It was then installed in the Catherine Palace in Tsarskoye Selo, Russia, until it was dismantled by German troops in just 36 hours in 1941 and moved to Königsberg Castle in East Prussia. Since 1945, amid Allied bombings, the Amber Room has disappeared without a trace, believed to have either been burned, buried, or sunk in the Baltic Sea.

It’s an armored 150-meter-long convoy rumored to be filled with 300 tons of gold, jewels, and stolen art. Allegedly, it vanished in May 1945 inside a secret network of unfinished tunnels in the Owl Mountains, near Walbrzych, Poland, as German forces fled the advancing Soviet Army.

Explorers and treasure hunters have launched many high-profile searches using groundbreaking technology to locate the train, but nothing has ever been found.

The Flor de la Mar ("Flower of the Sea") is a legendary Portuguese ship that sank in November of 1511, on its return from conquering a wealthy hub, now known as Malaysia. With it, an immense fortune estimated at $2.6 billion sank to the bottom of the ocean and was never recovered, making it one of the richest shipwrecks in history.

Over the centuries, countless marine salvage companies have attempted to recover the treasure, although political disputes over salvage rights between Indonesia, Malaysia, and Portugal have continuously interrupted such expeditions.

The Treasure of Lima is a massive fortune of gold, silver, and jewels (including a life-size solid gold statue of the Virgin Mary), valued at up to $208 million and missing since 1820.

It was stolen by British Captain William Thompson, who had originally been tasked with protecting the Spanish treasures and allegedly buried them on Cocos Island off Costa Rica, never to be seen again. When captured, he agreed to lead the Spanish forces to the gold, but instead escaped with his first mate into the thick jungle and vanished forever.

The infamous pirate Edward Teach, also known as Blackbeard, left behind a treasure no one has ever found. He terrorized the Atlantic Coast and the Caribbean, capturing numerous ships and stealing gold, silver, and valuable goods from them.

Modern estimates suggest that his riches would be worth $150 million. Before his death in November 1718, he claimed his wealth was hidden where "nobody knows but me and the Devil."

The Oak Island Money Pit is a centuries-old mystery of buried treasure filled with traps and tunnels, located in Nova Scotia, Canada. It began in 1796 when teenager Daniel McGinnis found a circular depression under a tree and started digging with friends.

As they dug, they began to find oak logs 10 feet down, pointing to a man-made shaft, but water from a storm later flooded the pit. Rumors suggest there is a vault with pirate gold from Captain Kidd, Spanish artifacts, or Marie Antoinette's jewels, as searchers have found tropical coconut fibers and fragments of gold chain there; skeptics suggest it might’ve just been a natural sinkhole all along.

Of the 50 Imperial Fabergé Easter eggs created for the Russian royal family, up to eight remain unaccounted for. Notable missing pieces include the "Nécessaire Egg" (1889), the "Cherub with Chariot" (1888), and the "Hen with Sapphire Pendant" (1886).

While many were lost or stolen during the 1917 Russian Revolution, miraculous findings, such as the "Third Imperial Egg" recovered at a U.S. flea market after a century-long disappearance, keep collectors' hopes alive.

The Honjō Masamune Sword is a priceless Japanese samurai weapon that was lost after World War II. It is considered one of the finest blades ever forged by the master swordsmith Gorō Nyūdō Masamune, and remains a priceless cultural symbol of power.

Designated an official Japanese National Treasure in 1939, many experts remain hopeful it might appear in a private collection or attic.

The Beale Ciphers Treasure is a renowned unrecovered fortune of gold, silver, and jewels, with an estimated value of over $65 million.

In 1820, a mysterious man named Thomas J. Beale checked into a hotel in Lynchburg, Virginia, and left a locked iron box with an innkeeper, alongside three encoded messages. If cracked, they supposedly reveal the hidden fortune. For now, only one has been decoded. Some experts allege the entire mystery is a hoax, while others continue to try to decipher the codes to this day.

The Lost Dutchman’s Gold Mine is a famous, undiscovered gold deposit, said to be hidden somewhere near Apache Junction, in Arizona’s Superstition Mountains.

Legend claims it was found by Jacob Waltz, a German immigrant (misidentified as Dutch due to the old use of the term "Deutsch"), who settled in Arizona in the 19th century and supposedly kept its location secret before dying in 1891, except for the verbal hints he allegedly gave to his neighbor Julia Thomas, sparking modern treasure hunting to this day.
