You might be surprised to learn that the world is filled with weird phenomena. Sometimes, truth is crazy than fiction. Here are some interesting facts to expand your knowledge.
First, natural honey lasts forever. In fact, scientists have found jars of honey in Egyptian pyramids that are millennia old and still safe to eat. This is due to its unique chemical composition which makes it difficult for bacteria to grow.
In the animal kingdom, octopuses actually have three hearts. Two hearts 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 read more tend to crawl rather than swim.
Here is another crazy tidbit: in terms of botany, watermelons are berries, yet raspberries are not actually berries. Biology can be tricky like that! On top of that, avocados are also considered fruit, not veggies.
To wrap things up, did you know that it is impossible to hum while pinching your nose shut? You can test it out yourself! The reason is that humming requires airflow to escape through your nasal cavity, and plugging it stops the sound.
These are just a few of the endless wonders in the world. Learning new things is a great way to pass time. Keep exploring!
