Discovering ‘Unbelievable but True’ facts is always a thrill. Their surprising truth ignites curiosity, challenges our understanding of the world, and adds a touch of wonder to everyday life. The real joy comes in that instant of amazement.
The realisation that something so extraordinary has been hiding in plain sight. Whether they spice up trivia nights, spark fascinating discussions, or make us see ordinary things differently, these facts never fail to entertain.
In this post, I’ve compiled a few jaw-dropping truths that will make you stop and say, “Wait, really?” Enjoy the read!
A Day on Venus Is Longer than a Year on Venus
Unbelievable, but it is true. As we know, one day is completed when a planet completes one revolution on its axis, whereas a year elapses when a planet completes one full orbit around the Sun. Venus, our closest neighbour, has a bizarre rotation pattern in the solar system. Venus takes only 225 Earth days to orbit the Sun, but it takes 243 Earth days to rotate once on its axis.
This makes a day on Venus longer than a year on Venus by 18 Earth days.
This slow rotation means that one side of Venus experiences extreme heat while the other side cools down considerably. The planet’s thick atmosphere, composed mainly of carbon dioxide, traps heat, leading to surface temperatures of around 475°C (900°F). This makes Venus practically an unhabitable place for any living organism.
There is more. Unlike most planets, Venus rotates in the opposite direction. So on Venus, the Sun rises in the west and sets in the east.
An Apple, Potato, and Onion All Taste the Same with a Plugged Nose
Sounds unbelievable? Well, eating is a multisensory experience. We relish food only when all our 5 senses are involved. Our eyes whet our appetite watching the colours and presentation. The Nose smells and triggers cravings even before the first bite. The tongue brings flavours together. The touch experiences the texture, and the ears hear the crunch and munch.
The sense of taste, however, is closely linked to the sense of smell. When our nose is plugged, we lose the aromatic input that enhances the perception of flavour. As a result, foods that have similar textures, like apples, potatoes, and onions, will taste the same. This phenomenon also explains why food seems bland when we have a cold.
Do you know that this true fact also makes airplane food bland?
At high altitudes, the cabin’s low humidity dries out our nasal passages, dulling our smell. The low air pressure reduces the sensitivity of our taste buds, and the constant engine noise mars our brain’s perception of taste and texture. All these together make the salty and sweet flavours less intense.
Bananas Are Radioactive
Don’t be alarmed but, it’s true.
Let me explain.
Bananas contain potassium, and about 0.012% of this potassium is a radioactive isotope, Potassium-40. Potassium-40 is naturally present in all potassium-containing foods. Apart from bananas, foods like potatoes, beans, and nuts also contain this trace amount of Potassium-40. While this sounds alarming, it’s completely harmless.
Potassium-40 has a very long half-life of approximately 1.25 billion years, meaning the radiation it emits is extremely low. The radiation from a banana is so insignificant that you would need to eat around 10 million bananas in one go to experience any harmful effects. The human body is naturally radioactive due to the potassium and other elements we consume daily.
The radiation emitted by bananas is also used as a reference point. It is known as the ‘Banana Equivalent Dose’. It is used to explain radiation exposure levels in simple terms. Thus, you can appreciate bananas not only for their taste but also for their intriguing scientific properties.
So, the next time you grab a banana, you can enjoy it without the fear of glowing in the dark!
Honey Never Spoils
Honey has very low water content and high acidity. Both these create an inhospitable environment for bacteria and microorganisms. While making honey, bees add an enzyme called Glucose Oxidase to honey. Glucose Oxidase produces hydrogen peroxide, which is a natural preservative. These factors together give honey an indefinite shelf life.
Archaeologists have found over 3000-year-old pots of honey in ancient Egyptian tombs. The honey was still perfectly edible! Good quality honey might crystallise over time. This doesn’t mean it has gone bad. Once you warm it, it will return to its gooey, golden goodness.
So, the next time someone throws out a jar of honey because it’s “too old,” tell them to store it as an ‘Unbelievable but True’ tale for their great-great-great grandchildren!
The Eiffel Tower Can Be 15 cm Taller During the Summer
Nothing unbelievable here. Just simple engineering and physics. The Eiffel Tower, which is 330 meters tall, is made of Wrought Iron. Wrought Iron is highly sensitive to temperature changes. As the summer sun blazes over Paris, the Iron in the tower absorbs heat and expands.
In other words, while the tower can grow taller by up to 15 centimetres during the summer, the tower can also lean slightly in one direction as different sides expand at different rates. Obviously, during the winter, the tower shrinks back to its original size.
While it sounds worrying, it is perfectly safe. Thermal expansion is a common phenomenon in metal structures. Engineers account for this when designing buildings and bridges, ensuring they can safely handle these size fluctuations.
So, next time you visit Paris in summer, remember that you are seeing a taller Eiffel Tower than your friends who visited it in the winter. Unbelievable but true!

The First Computer Bug Was a Real Bug
On September 9, 1947, something went wrong with the Harvard Mark II computer. The massive machine, a marvel of early computing, suddenly malfunctioned. Frustrated engineers pored over its intricate wiring, searching for the culprit. Then, they found it: a tiny moth, trapped between the relay contacts, disrupting the flow of electricity.
With a pair of tweezers, they carefully removed the insect. The incident was logged into the books as ‘First actual case of bug being found.’. The term “bug” had already been used informally by engineers to describe mechanical glitches. This incident helped solidify the term ‘Bug’ as a standard for computer errors.
The famous log entry was made by Grace Hopper, a pioneering computer scientist and U.S. Navy officer. Later, she played a key role in early programming and debugging techniques.
The original bug is preserved in the Smithsonian Institution, reminding us that even the smallest things can cause unbelievable problems in technology.
The Great Emu War of 1932
In 1932, Australia found itself at an unbelievable war with Emus (yes, Emus). These large, flightless birds went on a rampage in Western Australia. They destroyed crops and tormented farmers already struggling during the Great Depression. With no other viable solution, the government sent soldiers armed with machine guns to deal with the birds.
The great battle began in November. The soldiers opened fire on the herds of Emus, but the Emus proved shockingly resilient. Their long legs and swift movements made them hard to hit. Some birds even ran in zigzags to avoid the bullets. After weeks of relentless battle and thousands of rounds fired, the humans admitted defeat.
The Emus had outrun, outmanoeuvred, and outlasted their opponents. The army withdrew, and the emus reclaimed their territory. The Great Emu War remains one of history’s most bizarre conflicts. A reminder that sometimes, even machine guns are no match for nature’s soldiers.
One observer famously noted, “The Emus have won every round so far.”.
