We tend to take things in the world for granted Xi habitually, passing by them every day without thinking deeply. Sometimes, however, when we look at these things from a different perspective, we find that they also have an amazing side.
Here are some interesting facts about things that we are often exposed to in our daily lives that may surprise you.
1. The reason why cookies have holes.
If you think about it, you'll see that most cookies have holes in them, which is weird. The answer lies in the science behind baking, and it's all about steam. These holes allow steam to escape during cooking, preventing bubbles from forming and damaging the biscuits.
2. Cucumbers are classified as berries.
Cucumbers are classified as berries because they are grown from a single flower, which has only one ovary. In contrast, raspberries, although known as berries, are actually formed from multiple flowers, each producing its own seeds.
3. Elephants are the only mammals that can't jump.
Elephants are the only mammals that cannot jump. This is because their leg structure, unlike other mammals, lacks a "spring" structure capable of creating a bouncing force.
4. Chickens' earlobes can predict what color eggs they will lay.
The color of a chicken's earlobe can predict the color of the eggs they lay. Chickens with white earlobes will only lay white eggs, while chickens with dark earlobes will lay brown eggs.
5. Erasers don't just work manually.
Erasers are able to erase pencil marks because the adhesive particles of the eraser chemically react with the graphite on the pencil, rather than being removed by rubbing them alone.
6. You can smell rain for a reason.
When it rains, we are able to smell a special smell, which is due to the combined action of bacteria, plants, and lightning. The smell is known as "petrichor" and scientists have studied its long-lasting appeal.
7. Coffee beans aren't actually beans.
Coffee beans are actually the seeds of coffee cherries, which are a type of red or purple berries that grow on trees. These seeds are called coffee beans and are found inside the fruit known as "coffee cherries."
8. Human contraceptives are effective against gorillas.
The contraceptive pill used by humans is just as effective against gorillas, a discovery that provides scientists with a way to control the growth of gorilla numbers.
9. There's a reason we wake up feeling cold.
The reason why we feel cold when we wake up is because during sleep, our body's core temperature drops slightly. Even after we are fully awake, it takes a few hours for the body temperature to return to normal levels.
10. Bananas are radioactive.
Bananas are radioactive because they contain the element potassium, which is radioactive. Therefore, bananas have been reported to be one of the sources of radiation exposure.
