Curiosity is very important to all of us. The more we learn, the more we know. Curiosity is why humans are where we are today as the leading species on planet Earth. We've found, questioned, and found answers to many of life's mysteries. But there are still things that we see in our daily lives that bother us because we have no answers to them. Here are some simple questions we've always had that have finally been answered.

1 Who gets the middle armrest?

This is something many of us have dealt with while traveling. Whenever there are three chairs in a row, the dilemma comes from who gets the middle armrests. There is no answer here; it depends entirely on the people sitting on either side. If they think the middle person should get the armrest, the middle person gets the armrest.

2 Why is ice so slippery?

This is something many people would like to know. Ice gets its slippery character from the water that has melted but still remains on the surface. A block of ice without melted water is not smooth. The melted water on the ice surface acts as a lubrication between you and the surface.

3 What is the color of a mirror?

According to our eyes, mirrors have no color and just reflect back what it stands for. But the truth is that a perfect mirror reflects all colors that contain white light. But the real mirrors are not perfect because their surface atoms give every reflection a very light green hue, therefore the glass can reflect green light more strongly than any other color.

4 How does glue not stick to the inside of the bottle?

We all used some type of glue at some point in our lives. The most common and popular type is the liquid that comes in a tube or bottle. But have you ever wondered why the glue can stick to something, but not on the inside of the bottle it is in? This is because most adhesive formulas contain water that evaporates when it comes into contact with air. This will keep the adhesive molecules from curing on any surface to which it is applied.

5 His zebras are white with black stripes or black with white stripes?

For a long time, people have believed that zebras are white animals with black stripes. But the truth is the opposite of that. Zebras are black with white stripes. In the photo above you can see a baby zebra whose white stripes are not developed, which makes it look very different to its mother.
