It is a known fact that the universe is packed with bizarre phenomena. Sometimes, truth is stranger than fiction. Below are a few cool facts to feed your brain.
To start off, honey never spoils. Truth be told, explorers have found jars of honey in Egyptian pyramids that are over 3,000 years old and perfectly good to consume. This is due to its distinct chemical composition which makes it impossible for microbes to grow.
Moving on to animals, the octopus actually have three hearts. Two of them pump blood to the gills, while the other one pumps it to the rest of the body. Even stranger, when an octopus moves quickly, the heart that delivers blood to the body stops beating, which is why these creatures tend to scuttle rather than float.
Another mind-bending fact: scientifically, watermelons are classified as berries, yet strawberries are not actually berries. Biology can be confusing like that! On top of that, cucumbers are also fruit, not vegetables.

This is just a small sample of the thousands of wonders waiting to be learned. Discovering trivia keeps the brain sharp. Stay curious!
