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.

Fiction has given us worlds beyond comprehension—realms where logic collapses, physics defies expectation, and imagination reigns supreme. From cities in the sky to entire worlds beneath our own, some of these fictional places have captivated us since their creation. Join us on a fantastical journey through some of the quirkiest and most head-scratching of these imagined worlds.

Lewis Carroll’s 1865 Alice’s Adventures in Wonderland conjured a world where words, rules, and even size lose all meaning. Time halts at tea parties, cats vanish mid-sentence, and logic itself becomes nonsense.

Carroll, a mathematician and Oxford don, infused what at first glance seems like just a children’s story with riddles, puns, and complex paradoxes. The book’s wordplay critiques Victorian social norms while subtly introducing mathematical and logical concepts.

A technicolor realm of talking animals, magical shoes, and wicked witches, L. Frank Baum’s 1900 classic The Wonderful Wizard of Oz reshaped children’s literature forever. Baum’s storytelling introduced a vivid fantasy world filled with unique characters, whimsical landscapes, and moral lessons that appealed to both children and adults.

Characters like the Tin Man and the Cowardly Lion have become iconic figures in American popular culture for generations. The 1939 MGM film starring Judy Garland cemented the book’s imagery, leaving an enduring influence on film, theater, and the broader cultural imagination.

An island where no one grows up and pirates battle endlessly, J.M. Barrie’s Peter Pan debuted in 1904 and quickly became a lasting symbol of escapism. Barrie first introduced the character in a 1902 play before expanding the story into his 1911 novel, embedding themes of adventure, imagination, and the tension between childhood and adulthood.

Psychologists and literary scholars often reference Neverland as an allegory for arrested development, representing the desire to remain permanently in a state of innocence and freedom.

A wardrobe that opens to another world, talking lions, and epic battles of good versus evil—C.S. Lewis’s The Chronicles of Narnia (first published in 1950) created a richly imagined fantasy universe.

Drawing on Christian allegory, classical mythology, and his own experiences in World War I, Lewis crafted seven novels that explore courage, faith, and moral growth through fantastical adventures. The series has had a profound cultural impact, inspiring stage adaptations, radio dramas, films, and countless illustrated editions.

A floating island of science, invention, and eccentric rulers, Laputa appears in Jonathan Swift’s 1726 Gulliver’s Travels. The island hovers in the sky, controlled by magnets, and is inhabited by scholars obsessed with abstract mathematics, music, and astronomy—often to the detriment of practical life below.

Swift, a master of satire, used Laputa to lampoon the scientific and political elite of his time, highlighting their detachment from practical, everyday concerns. Its striking imagery has also had a lasting impact on the depiction of futuristic societies and utopian civilizations.

Rolling hills, cozy hobbit holes, and a peaceful, pastoral life—J.R.R. Tolkien’s Shire, introduced in The Hobbit (1937) and The Lord of the Rings (1954–55), embodies an idyllic, pre-industrial England beneath the veneer of a fantasy world.

Tolkien, a scholar of languages and mythology, infused the Shire with intricate customs, poetry, and festivals, aiming to create a mythology for England that he felt was missing—one that celebrated simplicity, community, and harmony with nature.

A hidden plateau where dinosaurs and prehistoric creatures survive, Arthur Conan Doyle’s 1912 novel The Lost World introduced readers to a thrilling world untouched by time. Doyle’s story follows Professor Challenger and his expedition as they encounter giant reptiles, ape-men, and other wonders on a remote South American plateau, blending adventure with early paleontological speculation.

Doyle was likely inspired by Mount Roraima, a flat-topped plateau in South America’s Guiana Highlands. Its sheer cliffs, isolated ecosystem, and mysterious cloud-covered summit provided a tangible model for the novel’s prehistoric world.

A legendary sunken city, Atlantis was first described by Plato in his dialogues around 360 BCE. According to Plato, Atlantis was a powerful and advanced civilization that sank beneath the ocean in a single day and night of catastrophic events, serving as a cautionary tale about hubris and moral decline.

Despite its origin as a philosophical example, many scholars believe Atlantis was inspired by the real-life Minoan civilization on Crete. The Minoans were an advanced maritime society whose cities, such as Knossos, were eventually devastated by natural disasters, including the volcanic eruption of Thera (Santorini) and subsequent tsunamis.

A hollow Earth filled with prehistoric creatures and lost civilizations, Edgar Rice Burroughs’s Pellucidar (1914) imagines a world at the center of the planet, lit by an eternal inner sun. The series follows David Innes and his adventures among tribes of humans, dinosaurs, and other strange beings, blending swashbuckling action with imaginative geography.

Burroughs drew inspiration from the era’s fascination with unexplored frontiers and the Hollow Earth theories popular in the 19th century. Pellucidar has influenced later science fiction and adventure literature, inspiring works that explore hidden worlds and isolated ecosystems.

A mysterious Scottish village that appears for only one day every hundred years, the legend of Brigadoon draws on deep-rooted folklore from the Scottish Highlands. The tale likely originates from myths of fairy-haunted glens and hidden villages, where magic protected communities from outsiders and the passage of time.

Such stories often emphasized the danger and allure of the supernatural, reflecting local beliefs about enchanted landscapes and the thin boundary between the human and fairy worlds.
