Curiosity is a driving force behind human thinking. Asking questions also inspires imagination and innovation. Therefore people should always be encouraged to ask questions about any possible topic. Sometimes, however, our burning questions are very difficult to find answers to.

1. Who gets the middle seat armrests

There is no official law on who the armrests of the middle seat belong to. Many etiquette experts, however, come to the same conclusion: the individual caught in the middle needs power over them and that’s why.

The person sitting by the aisle has the benefit of extending both legs while the person at the window has the advantage of leaning against them while they enjoy the view and monitor the sun. But the person in the middle can not move or stretch easily, nor is there somewhere to lean on them.

2. Why plastic soda bottles have bumpy bottoms while water bottles don’t

The bumps are there to make the bottle more strong. This is necessary because the plastic bottle must be in a position to withstand the gas pressure in soda. Often, these drinks are generally served chilled, and as a liquid gets colder, the volume decreases, and because of that, the bottle must not buckle.

As an extra, the bump’s corner or tip can expand and contract slightly, without breaking. That also takes care of the change in volume.

3. Why flies can never find the open window

Flies have compound eyes that allow them to make a very accurate distinction between light and dark. The only thing they seek when roaming around your room is a source of light. Even though an open window is a light source, it also provides a flow of air into space from outside. This wind creates an atmosphere in which the insect is not very keen to fly in, resulting in it avoiding your window and looking for another source of light.

4. Why ice is slippery

Ice is only slippery when you walk on it, and it’s near a point of melting. Slipping is caused by the rolling of molecules over water that can not be bound to other surface water molecules. You may compare it to a dance floor that has marbles or balls on it.

5. Why cats purr

Most people believe that cats rumble out of pleasure as the sound often seems to occur at times when your cat seems to love being held. However, purring has been found to possess communication and healing properties. Researchers have also found that the purring of cats creates frequencies that are used to relieve pain, oedema, wounds and dyspnea. It could also explain why plenty of cat owners consider cuddling soothing with their furry mates.

6. The real colour of mirrors

A perfect mirror represents all current colours backwards. The scientific white light concept consists of a combination of all current colours. A mirror is also said to be white, for that reason.

7. Why sloths are so slow

The diet of a sloth is based almost entirely on leaves which are very poor in nutrients, meaning the animal has a small calorie intake. Climbing is an everyday activity that can be very demanding because they live in trees. We travel incredibly slow and have a very high metabolic rate and cope with low-calorie intake.

8. Why glue doesn’t stick to the inside of the bottle

Most glue contains water as a solvent which holds it inside the bottle in a thick, liquid shape. Only when you squeeze it out of the pipe and apply it to a surface will it become sticky. The water present in the glue evaporates when in contact with the surrounding air, thereby making the glue harden. The only remaining things are sticky molecules which hold objects together.

9. Why wedding dresses are white

Most women married in the 19th century in a dress that they could reuse for other occasions. White wedding dreams were later sparked by Hollywood movies happily-ever-after, but usually, only rich families can afford to purchase a white dress. Middle-class people only began copying the look in the 1950s, thanks to the development of cheaper materials during the post-war prosperity boom.

Yet not all cultures wear white wedding dresses even today. For example, brides wear red dresses in China and India, as a symbol of good luck and success.

10. Zebra’s stripes

There has long been a common misconception that zebras with black stripes were white animals. It does turn out to be the contrary, however. The original Zebras colour is black. The white stripes emerge only later as an embryo of zebra develops in the belly of the mother, which can be clearly spotted in the picture above where one zebra’s white stripes did not develop well.

11. Why orange juice tastes horrible after brushing your teeth

Toothpaste messes a little with the taste buds. It suppresses the ability to taste sweetness which means that certain tastes are more pronounced, such as orange juice. As a result, its sweetness is repressed as its bitterness increases and suddenly your tasty beverage becomes undrinkable.

12. Why your palms sweat when you’re nervous

Sweat from the stress comes from nervous excitement. Your body releases adrenaline which sets your heart to pound to be ready for everything that comes next. Sweating has the main function of controlling body temperature for when your body goes to work. The sole of the feet and the palms of the hands are parts of the body with the highest concentration of sweat glands.
