Winter Hat Pom-Poms
It looks like a lot of people fail to keep their head comfy and warm when the winter season rolls in. Hats are a good way to fix this problem. However, you might start to wonder what the pom-poms on some of them are for. The feature has roots in Scandinavia! They were added to collect the seams during the knitting process. While other materials have since been used, this adorable little feature lives on.

Airplane Window Holes
We bet you also freaked out when you first noticed that tiny hole located in the airplane window! Relax, everyone has been there at some point. But why do they exist in the first place? These things are called breather holes. They let the outer panes of the plane handle the pressure difference as the vessel gets higher and higher. It lets the cabin remain at a safe and comfortable level the whole time. If the outer pane is ever compromised, there should be an air leak through there. Make sure to keep an eye for that!
