You might be surprised to learn that the world is teeming with bizarre phenomena. Sometimes, real life is stranger than fantasy. Below are a few cool facts to expand your knowledge.
Let's begin with this: honey never spoils. Actually, scientists have discovered jars of honey in ancient Egyptian tombs that are over 3,000 years old and perfectly good to consume. It is due to its unique chemical composition which makes it impossible for bacteria to survive.
Moving on to animals, octopuses actually have three hearts. Two hearts pump blood to the gills, while the other one pumps it to the organs. Interestingly, when an octopus swims, the heart that delivers blood to the body takes a break, which is why these creatures tend to scuttle rather than float.
Here is another weird fact: in terms of botany, bananas are berries, however, raspberries are not actually berries. Biology can be confusing like that! Additionally, cucumbers are also considered fruit, not vegetables.
Finally, were you aware that it is impossible to make a humming noise while holding your nose? You can test it out fact right now! The reason is that making that sound requires air to pass through your nose, and blocking it prevents the vibration.
This is just a small sample of the thousands of wonders in the world. Gaining knowledge makes you more interesting. Keep exploring!
