Winter Hat Pom-Poms
The pom-poms that come with winter hats which keep the head warm during winter are a fashion feature that can be traced to Scandinavia. During that period, knitting was still quite common and in order to gather the seams, pom-poms were added. Nowadays, pom-poms are just an adorable feature which has lived on!
Airplane Window Holes
That tiny hole in the airplane window that freaked you out is actually very useful. The breather hole allows the plane’s outer panes to manage the pressure difference as the aircraft goes higher. This keeps the cabin comfortable and safe. You would know if the outer pane got compromised because there will be an air leak through the breather hole!
