Children’s Questions That Adults Don’t Have the Answers To

If you have children, at least once in your life you have probably received questions from them you didn’t have the answer to. For example, have you ever thought about why passports only have certain colors or why people cannot smile in ID photos? There are plenty of things that have certain features but sometimes we don’t even ask ourselves “why.”

We at Bright Side were eager to find some interesting questions that our kids may ask us about. So after reading our article, we are sure that you will be able to answer them all!

1. Why can’t you smile in your ID photos?

Every time we take photos for passports, visas, or documents the requirements say that a neutral facial expression and closed mouth are the “must.” The reason is the biometric scanners that were launched in 2005. The scanners can only recognize a person’s face if it stays neutral which allows for the prevention of fraudulent use.

2. Why do passports never come in orange or purple?

Which color is your passport? We bet it is either green, grey, red, blue, or black. Although there are some color variations that are used in particular countries only, you will never see lime green, orange, or purple passports. Why? Actually, there are no specific requirements, countries just don’t use bright colors because they do not look official and serious.

3. Why do most people hate the sound of their own voice?

You’ve probably heard your recorded voice and didn’t like it, and you are not the only one here — there is even a special term for disliking your voice — “voice confrontation.” The thing is that the conductivity of air and body tissue is different, and vibrations inside the body make us think that our voice is actually lower.

But if we hear our voice in a recording, then the brain receives information about sounds only through the auditory nerve — and this is how this dissonance appears. Our recorded voice doesn’t meet our expectations and this is where the disconnect happens.

4. Why are tennis balls yellow?

The tennis ball has undergone an evolution of colors. Before having its yellow neon color, the balls were either white or black. But the problem was that it was difficult to spot the ball on a TV screen. So eventually the sports community decided to make all balls yellow so they could be visible to the audience.

5. Why are school buses and taxis also yellow?

Taxi cabs and school buses have something in common — their yellow color. The reason behind this is quite simple — yellow catches attention faster than any other color. Among other objects, you spot yellow things first even in darkness. Hence this color was chosen for school buses and taxis, so children and adults could easily spot it.

6. Why does aluminum foil have a shiny and a dull side?

If you have ever used aluminum foil you have probably noticed that it has 2 sides — dull and shiny. Maybe you were thinking that there is a ’right part’ that should cover the food, but the reason is in the manufacturing process. During ’milling’ when heat and tension are applied to stretch and shape the foil, the 2 sides are pressed together and milled at the same time. This helps avoid the breakage of the foil.

7. Why does a soda in cans and plastic bottles taste different?

If you are a fan of soft drinks, you have probably noticed that soda in cans tastes different from soda in bottles. Even though manufacturers use the same formula for different packages, many people think that canned soda tastes a bit milder. The possible explanation is that the aluminum in cans has a polymer lining which may absorb some flavor. And in the case of bottled form, the taste is different because of the plastic chemical — acetaldehyde that also alters the flavor.

8. Why do sunset and sunrise look different?

Can you spot the differences between sunset and sunrise aside from the upward and downward trending sun? You may have noticed that they have different colors.

The explanation is that the path of rays during dusk and dawn is much longer than during the day. Before sunlight reaches our eyes, shorter wavelengths are scattered and we see the colors like yellow, orange, red during sunsets. However, at sunrise, the darkness of the night left us with very keen night vision, and every faint, slight change in the color of the sky is obvious. So we perceive more colors at dawn than at dusk.

9. Why do we have dark circles under our eyes when we are tired?

After sleepless nights and hard work, we may notice dark circles under our eyes that women usually try to hide using cosmetics. According to doctors, the circles appear because fatigue and lack of sleep may slow the blood circulation around the eyes. And because of this, the capillaries (blood vessels) situated in this area swell up with blood and dilate, making the skin under our eyes darker.

10. Why don’t we remember our dreams sometimes?

Sometimes after a night of sweet, sweet sleep, we can remember our dreams, but sometimes we can’t. The reason is rooted in the biology of our sleeping bodies and subconscious mind. Dreams we remember mostly happen during certain periods in our sleep cycle. But if we wake up with an alarm clock it spikes our noradrenaline levels and makes it harder for us to remember our dreams.

Can you come up with other “kid” questions that we as adults do not always have the answers to?
