Mirrors are reflective due to a thin layer of metal, typically aluminum or silver, coated on their surface. This metallic layer reflects light rather than absorbing it, allowing us to see a clear image of ourselves or our surroundings. The smoothness of the reflective surface ensures that light reflects uniformly, leading to a sharp and clear reflection.

Mill owners had to offer high wages to attract women to work as mill girls because the labor market was competitive and many women had other options, such as domestic work or family responsibilities. Additionally, the physically demanding and often harsh conditions of mill work made it less appealing, necessitating higher pay to entice women to leave their homes and join the workforce. The promise of financial independence and better living standards also played a role in drawing women to these jobs, despite the challenges.

If you have a stuck object in your ear, such as a small tunnel or earring, avoid using cotton swabs or any tools that could push it further in. Instead, try tilting your head to the side and gently pulling on your earlobe to see if gravity helps dislodge it. If that doesn't work, consider using a few drops of mineral oil or baby oil to lubricate the area. If the object remains stuck, it's best to seek professional medical help to safely remove it.
