Winter Hat Pom-Poms
Winter hats are essential in keeping our heads warm and comfy in the winter, but have you noticed the pom-poms which sometimes come with these items of clothing? The fashion feature can be traced back to Scandinavia. When knitting was still really common, the pom-pom was added to gather the seams. This is not the case anymore, but the adorable feature lives on!
Airplane Window Holes
You might have noticed a tiny hole in the window of the airplane when you sat in the window seat and freaked out a little, but do not worry because you are not alone. Maybe you are wondering why it even exists. Well, it is called the breather hole and it lets the airplane’s outer panes manage the pressure difference during the times the airplane flies higher. This allows the cabin to stay at a safe and comfortable level. If the outer pane ever got compromised, an air leak should be noticed through the tiny hole!
