Necessity is the mother of invention

Nutella, bras, and instant ramen: 10 things created out of necessity

Nothing gets the human mind going like needing something and not being able to get it. When common items are in short supply due to a crisis, the human mind always finds a way to get something like it, or even better.

Crises such as war, famine, recessions, or natural disasters have shocked humanity and forced it to be resourceful. Let’s have a look at ten things that originated out of necessity.

The world runs on caffeine, and also does war. During the American Civil War, the Union army produced a water-soluble coffee concentrate, made from a mixture of coffee, milk, and sugar. The resulting ‘coffee’ was said to look like grease, and tasted so awful that it was discontinued.

This invention was not successful, but it was a starting point that pioneered the development of soluble coffee as we know it by the end of the 19th Century. In the 1910s, Red E Coffee became the first instant coffee to achieve success, and the development of Nescafé two decades later made the drink a global sensation.

Japanese cuisine is strongly dominated by rice, so why is one of its star products made from wheat? After World War II, Japan experienced a food shortage, especially rice, which led the government to promote the consumption of wheat bread.

Trying to figure out a way to produce shelf-stable wheat noodles—a food item more familiar to the Japanese than bread—Momofuku Ando developed in 1958 a system to flash-fry noodles that were easy to rehydrate. In 1971, Momofuku also developed cup ramen, which popularized instant noodles worldwide.

The widespread use of chemical warfare during the 20th century meant that antidotes were essential on the battlefield. But how to deliver the exact dose in the quickest way possible? In the 1970s, engineer Sheldon Kaplan and his colleagues created the ComboPen, a system that used pre-measured doses in glass containers and a spring mechanism to administer the injection.

This new system not only helped with quick treatment on the field, but the concealed needle also made the process easier for those with a fear of needles. Furthermore, it can be used by anyone, even those with little to no medical training. After successfully testing the ComboPen, they realized it could be used for other emergency medications, such as epinephrine, creating this way the EpiPen.

Corsets were not the torture device some people imagine, but they were the main supportive undergarment used by women up to the early 20th Century. By that time, most corsets had metal boning, but the material was rationed for ammunition during World War I.

When the shortage of metal boning made corsets go out of style, women turned to the Brassiere —what we would now call a bra, which existed already, but was not popular— for support, making it the standard garment.

If you go to Vietnam (or a Vietnamese coffee shop), you will certainly find egg coffee on the menu. This thick and creamy drink, sweetened with condensed milk, is a Vietnamese staple and an ingenious response to food shortages.

During the 1940s, at the start of the First Indochina War, basic food items were difficult to come by. In a luxurious Hanoi hotel, bartender Nguyen Giang is trying to figure out how to make café au lait without milk. He gets the idea to use an egg yolk, which froths up just like milk does, giving coffee a creamy consistency that pairs well with sweetened condensed milk, a staple of Vietnamese cuisine. Egg coffee became so popular that Nguyen opened his own shop in Hanoi in 1946, which is still standing.

Although this canned processed meat is an American invention, it’s also a fairly common ingredient in countries like Korea, Japan, and the Philippines. SPAM was one of the main rations sent to American soldiers during World War II and the Korean War. They were sent so much SPAM that they grew tired of it, selling or giving away the surplus.

Locals had a hard time finding meat, so SPAM was quickly adopted into their cuisines, and is now featured in popular dishes such as the Korean budae jjigae (which means ‘army base stew’), the Japanese SPAM onigiri, or the Philippine spamsilog (a breakfast of spam, fried rice, and eggs).

Nutella is widely known for its chocolate and hazelnut spread —a version of the Italian _gianduja_—, but did you know it has its origins in a food shortage? At the start of the 19th century, Napoleon Bonaparte had established a blockade, intended to prevent British goods from entering territories under French control.

In the city of Turin, Italy, the blockade diminished the cocoa supplies. To combat this, chocolatiers mixed the cocoa with chopped nuts —mainly hazelnuts— to stretch it, creating the gianduja.

Japgokbap or multigrain rice is a Korean staple dish, and one that was born out of necessity. Korea has always been a fertile country suited for agriculture, but this has not prevented its citizens from experiencing famine and struggles. During the Japanese occupation (1910–1945), Korean farmers were forced to grow Japanese rice instead of their native variety to address the food shortage in Japan.

With their main food source being scarce, Koreans had to rely on other grains like millet, sorghum, or corn. They mixed these grains with beans, and the small rations of rice they could get to make it more filling and nutritious, in a dish they called Japgokbap, and that saved thousands from famine.

For people prone to accidents, Band-Aids are a lifesaver that keeps minor wounds clean and protected. They were created with this goal in mind, but they became popular out of financial necessity.

Band-aids were invented in 1920 by Earle Dickson, who was inspired by his wife’s regular accidents in the kitchen and needed a quick way to dress the wounds without assistance. A few years later, the financial struggles of the Great Depression meant that people weren’t always able to get medical assistance, and started relying on Band-Aids to treat domestic wounds.

Many cultures eat offal, but not all started doing it out of necessity. In Argentine barbecues, offal (called achuras, a native word meaning ‘what is discarded’) is a staple alongside cuts of meat and sausages, but this was not always the norm.

South American meat is renowned for its quality, but there was a time when some parts of the cow were considered unsuitable for consumption. These discarded parts, from the brain to the intestine and everything in between, were recovered by the lower classes and made their way into Argentine cuisine, where nowadays every last part of the cow is consumed.

The 12 longest-living animals on Earth (and how they cheat time)

Nature doesn’t just create beauty, it crafts survival miracles. While most animals have short lives, a rare few have mastered the art of staying alive for centuries, even millennia. These aren’t just long-lived creatures; they’re nature’s ultimate time travelers. From the frozen depths of the oceans to the darkest corners underground, they’ve developed bizarre, brilliant strategies to cheat death. Get ready to meet 12 animals whose lifespans will absolutely blow your mind.

Record age: up to 15,000 years

This unassuming sea sponge thrives in the freezing waters of Antarctica, where temperatures hover around 28.6 °F—so cold that biological processes hit the brakes. In such icy conditions, metabolism slows to a crawl, allowing these sponges to live for thousands of years.

Some have reached impressive sizes of over 3 feet tall and have been around since mammoths were still thundering across the tundra. They don’t move, they don’t stress, and they barely change, just quietly existing while centuries pass them by. Their secret to extreme longevity? Glacial patience, deep-sea stillness, and a lifestyle that redefines "low-maintenance".

Age: technically… infinite

This tiny jellyfish, no bigger than a fingernail—less than 0.2 inches—is like the ocean’s very own Benjamin Button. What makes it truly extraordinary is its ability to rewind its life story, flipping back to a youthful, juvenile stage whenever it wants. While it’s not completely invincible (predators and other threats are still very real), if left undisturbed, it can keep hitting the reset button on aging indefinitely, making it one of the most fascinating "time-benders" in nature.

Record age: 507 years

In 2006, a special clam was discovered buried deep in the seabeds of the North Atlantic. Scientists were able to determine that it had been there since at least 1499—that’s centuries before the United States was even a thought! This ancient marvel, nicknamed "Ming", was able to perfect a slow-and-steady approach to life. Growing at a snail’s pace and barely budging, Ming’s sedentary lifestyle turned out to be a brilliant strategy for beating the clock. Who knew doing almost nothing could be the ultimate secret to longevity?

Record age: estimated 392 years

These sharks aren’t your average ocean cruisers—they can stretch over 20 feet long and weigh up to 2,200 pounds. But what’s really mindblowing is how slowly they move, like they’re in a permanent state of deep relaxation. Living in the icy Arctic waters, these giants don’t hit adulthood until they’re about 150 years old, and some can glide through the depths for nearly 400 years. Imagine that! These ancient swimmers were already around before America declared independence... and they are still out there, silently roaming the seas!

Record age: over 211 years

This whale is a true ocean giant, stretching up to 60 feet long and weighing a staggering 200,000 pounds. But what makes it stand out isn’t just its size but its age. Some of these majestic creatures carry harpoons from the 1800s still lodged in their skin, like walking history books. Just picture living so long that you’re literally carrying outdated technology embedded in your body—talk about being a time traveler of the seas!

Record age: 200 years

Spanning the chilly Pacific coastline from California all the way up to Alaska, this spiky little ball—about 7 inches across—is full of surprises. It munches on algae and calls the deep, dark ocean its home, thriving at depths of up to 300 feet. Don’t let its size fool you: this prickly creature is a true elder of the cold seas, quietly outliving many ocean neighbors while keeping a low profile. A tough, slow-living veteran wrapped in spikes!

Record age: 226 years

Meet Hanako, a legendary Japanese koi who swam through life for an astonishing 226 years. Scientists discovered how old she was by studying the rings on her scales, much like counting the growth rings of a tree. These colorful, ornamental fish aren’t just symbols of good fortune; they’re also secret long-lifers with the potential to celebrate over two centuries of birthdays, as long as they get the right care and a peaceful pond to call home.

Record age: 190 years

Jonathan is a male tortoise living on the remote island of Saint Helena in the South Atlantic Ocean. He was born back in 1832, and he’s still happily chomping lettuce and soaking up the sun today. Weighing in at more than 400 pounds and measuring around 3 feet long, Jonathan holds the title of the oldest known living land animal on the planet. If he could share tales, they’d span nearly two centuries of history. Imagine that!

Record age: 152 years

This ancient-looking fish, with its whisker-like barbels, looking like a tiny underwater submarine, prowls the lakes of North America. It can reach an impressive length of up to 7 feet and weigh around 200 pounds. These slow-living creatures don’t rush into adulthood—they start breeding only around age 20—and then take their time cruising through life at a leisurely pace. Believe it or not, one legendary catch in Wisconsin was estimated to be over 150 years old!

Record age: over 90 years

This chunky, night-loving parrot from New Zealand is a true oddball—it can’t fly, snores like a grumpy grandpa, and smells like fresh flowers. Despite its quirks, this bird boasts an impressively long lifespan. Sadly, it teeters on the edge of extinction. The oldest known kakapo, affectionately named Richard Henry, lived 90 years, earning him the title of the charmingly eccentric elder statesman of the avian world.

Record age: 37 years

This tiny, kooky rodent—barely 3 inches long and just over an ounce in weight—could’ve been cast straight from a sci-fi apocalypse flick. Dwelling in vast underground colonies across Africa, it’s practically invincible to cancer, pain, and the usual effects of aging. Scientists are fascinated by this little marvel, even if it’s not winning beauty contests anytime soon. Its superpowers make it a star in longevity research!

Record age: estimated 100+ years

Lobsters have a totally different rulebook than us when it comes to aging. They don’t really grow old; they just keep getting bigger and bigger. Some giant lobsters weigh over 40 pounds and stretch beyond 3 feet long. Their biggest threats? Not old age, but predators or the risky process of shedding their shells. In theory, they could live forever if left alone—but let’s be honest, not many get to enjoy a peaceful, lobster-sized retirement!
