–“The tiny holes (think Tom and Jerry Mouse holes) at the bottom of doors in Antarctica serve a practical purpose related to air pressure. In Antarctica, where buildings are heated and the outside environment is extremely cold, a significant difference in air pressure can develop between the inside and outside of a structure. These small holes help equalize the air pressure, preventing doors from becoming difficult to open or close due to pressure differences. This is particularly important in such an extreme environment where maintaining the functionality of doors and ensuring easy access to and from buildings is crucial for safety and operational efficiency.”–
