Some facts can sound true while they are false, whereas some sound farfetched but are actually true. In a world where technology is rapidly advancing, we try to stay up to date with the most trending information. However, no matter how hard we try, there will always be so much we don’t know. For instance, did you know that the selfie was not invented by millennials, or that human teeth are just as strong as that of a shark? To feed your curiosity, here’s a list of totally random facts that will actually surprise you.
1. Food manufacturers deliberately design chips to be crunchy. The process subconsciously convinces you that the chips taste good, making you crave for more.
It is a common perception that the crunchier the food, the better it tastes. This is because our brains compare the crunchiness with the freshness of the food. According to a leading scientist, manufacturers deliberately make the packaging loud because the chips taste fresher if you can hear the rustle. In order to further prove the effect, researchers conducted a “sonic taste” experiment where subjects were asked to eat chips while wearing headphones. Since the subjects did not hear the crunchy sound, they reported that the chips tasted stale and spongy. When the same bag of chips were eaten by the subjects without their ears covered, they reported them to be fresh.
Charles Spence, a professor of experimental psychology at Oxford University, who conducted the study, concluded that sound, as well as smell, plays a huge part in our enjoyment of food. He said: “The sound of the food matters. The sound of the packaging matters and atmospheric sounds matter”. This effect, he believes, is something the chip makers use to their advantage. (source)
2. Millennials didn’t invent selfies. The world’s first selfie was taken by an amateur photographer in 1839 using a homemade camera.
It is a common misconception that the selfie is a millennial invention but little did you know, selfies actually existed long before the modern camera. In fact, the first ever recorded selfie was taken by Robert Cornelius, an amateur photographer, in 1839 using a homemade camera and chemicals. The world’s first-known photographic self portrait or selfie was taken by a Dutch immigrant’s son. In 1840, the very next year, Robert Cornelius opened Philadelphia’s first portrait studio—the second such studio in all of America. (source)
3. Butterflies actually taste using their feet.
As humans, we taste using our tongues, listen using our ears and see with our eyes. When it comes to butterflies however, things are a bit different. According to National Geographic, some insects taste with their feet and hear with their wings. The butterfly is one such insect that has taste receptors on its feet. Since butterflies rely on the nectar of flowers to survive, they have to hop on hundreds of flowers every day. So, it makes sense that their taste receptors are on their feet. As soon as they land on a plant or flower, the taste receptors tell the insect whether it is safe for their offspring to eat when they hatch as caterpillars. (source)
4. Human teeth are just as strong as a shark’s teeth.
While human teeth are nowhere close to the size or number of a tiger shark, scientists discovered that they are just as strong. The surprising discovery was made when scientists compared the micro-structure of human and shark teeth. During the study, they discovered that the top ocean predator’s teeth are coated with extremely tough enamel but they are no stronger than the teeth found in your average human being. ‘This is due to the special micro and nanostructure of our teeth,’ said lead researcher Professor Matthias Epple, from the University of Duisburg-Essen in Germany.
‘The crystals in human teeth have a special arrangement and they are ‘glued together’ by proteins which stop cracks from running through the whole tooth’. The research, which is published in the Journal of Structural Biology, could help scientists around the world to design stronger and longer lasting dentures. (source)
5. Birds are capable of seeing colors that are invisible to humans.
“Our clothes were pretty drab before the invention of aniline dyes, but then color became cheap and there was an explosion in the colorful clothes we wear today,” says Richard Prum, professor of ornithology, ecology, and evolutionary biology at Yale University. “The same type of thing seemed to have happened with birds”.
According to a new study, which is published this month in the journal Behavioral Ecology, birds not only can see more colors than they have in their plumage, but because of additional color cones in their retina, they also see colors that are invisible to humans. “The startling thing to realize is that although the colors of birds look so incredibly diverse and beautiful to us, we are colorblind compared to birds”, says Richard Prum.

6. There is a species of jellyfish that can live forever by regenerating its cells in times of crisis.
While we often joke that cats have nine lives, there’s a certain species of jellyfish that has been deemed immortal by scientists. The jellyfish, known scientifically as Turritopsis nutricula, was discovered in the Mediterranean Sea in 1883. However, scientists did not learn about its ability to regenerate cells until the mid-1990’s. According to scientists, when a mature Turritopsis is under crisis, it attaches itself to a surface in warm ocean waters and converts into a blob. From this state, it undergoes transdifferentiation in which the cells essentially transform into different types of cells. So, every time it ages or comes under stress, the Turritopsis reverts to an adolescent phase and restarts. (source)
7. Crocodiles are also biologically immortal.
Unlike other reptiles, mammals or humans, crocodiles do not go through senescence, or gradual deterioration of the body with age. Crocodiles are one of the few species that exhibit Negligible Senescence, which means that they show almost no signs of aging, or they are ‘biologically immortal’. According to scientists, a 7-year-old crocodile is as good as a 70-year-old one in terms of agility and other life parameters. Aging has no effect on them… but how they cease to exist? In reality, they disappear due to starvation or disease. Crocodiles grow and keep growing throughout their lifespan. As they keep growing, their body requires more food; which they would not be able to find. This is one of the only two ways that they disappear off the face of the Earth. (source)
8. Saudi Arabia imports camels and sand from Australia.
When we hear Saudi Arabia, the sandy barren deserts and camels come to our minds. However, you would never imagine that Saudi Arabia would have to import the sand and camels from Australia. As it turns out, they do. Aussie companies export sand and camels to Saudi Arabia and for a reason. Saudi Arabia imports heavy mineral sand for sandblasting, a high-pressure technique to smooth and clean hard surfaces in buildings. According to the Daily Telegraph, more than 6 billion worth of sand is exported every year from Australia to Saudi Arabia. (source)
9. The location of the world’s tallest tree, Hyperion, has been kept a secret from all but a few select scientists.
The crown of Hyperion, a roughly 600-year-old coast redwood tree, standing more than 379 feet tall, is located in a remote part of Redwood National Park. It’s the tallest tree on Earth and in order to protect it, the National Park Service does not tell anyone the exact location of Hyperion. In fact, in order to close guard the secret, the park rangers don’t even mention the tree by its name. The Hyperion is a close guarded secret because adventurers wish to scale it and photograph their achievement. Only a handful of park rangers and some scientists who study the tree know the precise location. (source)
10. Betty White (97) is older than sliced bread, the microwave, ballpoint pen, trampoline, instant coffee, garage, traffic signal, automatic watches, instant camera, jukebox, garbage disposal, sunglasses, frozen food and rubber tires.
When you think of Betty White, the first thing that come to your mind is The Golden Girls. Born on January 17, 1922, Betty White is one of the most famous and recognizable figures in the world. Everyone’s favorite white-haired superstar is 97 years old, which is not only older than billions of people, but also older than a lot of everyday inventions. The first automatically sliced commercial loaves were produced on July 6, 1928, in Chillicothe, Missouri, using a machine invented by Otto Rohwedder, an Iowa-born, Missouri-based jeweler. (source)
