There are always some questions for small things you encounter in your daily life. Here are 15 answers to things you've always wondered about.

1. Why do your fingers and toes get wrinkly in the shower?

Why do your fingers and toes get wrinkly in the shower

Scientists have figured out why our fingers and toes get wrinkly during bath-time. This is because the outer layer of skin on your hands and feet — called the epidermis — is different than the skin on the rest of your body. The thicker layer of skin on your hands and feet contains more dead skin cells than other parts of your body. These dead skin cells soak up water like an efficient sponge, while thinner skin on the rest of your body is less affected. The good news is that wrinkled fingers and toes are a painless, temporary situation. The human body is amazing.

2. If our blood is red, why are our veins blue?

If our blood is red, why are our veins blue

Skin absorbs blue light. Subcutaneous fat allows blue light to penetrate skin all the way to veins, so this is the color that is reflected back. Less energetic, warmer colors are absorbed by skin before they can travel that far. Blood also absorbs light, so blood vessels appear dark.

3. Why is the sky blue?

Why is the sky blue

Much like our veins appear blue, it has everything to do with wavelengths and blue light. Blue light scatters more than the other colors in the spectrum because it travels as shorter, smaller waves.

5. Why do we say "cheese" when we get our pictures taken?

Why do we say

The origin is unknown, but when you say "cheese," the act of saying the word turns the corners of your mouth lift up, your cheeks lift, and you show off a toothy grin. It looks like a smile, and since smiling is what we do in pictures, the instruction seems pretty practical.

6. Why Do Stores Blast Air At Entrances?

Why Do Stores Blast Air At Entrances

It is a fairly common occurrence to be blasted with air upon entering a store or mall. It is to keep the temperature in a building steady by preventing air from leaving or going in through an entrance. The jet of air is used to keep cold air out of the stores during the winter and to prevent cool air escaping during the summer. Air doors are also incredibly useful for stopping flying insects from entering a building by providing turbulent air that they cannot pass through.

7. What Causes Butterflies In Your Stomach?

What Causes Butterflies In Your Stomach

The fluttery feeling in the gut can occur for a variety of reasons, from being scared or nervous because of an upcoming event. Different emotions can cause sensations and physical changes in your stomach thanks to the so-called “brain-gut axis.” Feelings in the brain, such as fear or excitement, are interpreted as stress and activate the fight-or-flight response. This releases extra adrenaline into the body to help us either combat a threat or get away from it by increasing blood flow to the heart, lungs, and muscles. With only a limited amount of blood in the human body, less of it can flow to other organs, such as the gut, which leads to butterflies in stomach.
