[00:00:00]Have you ever noticed [music] this tiny hole in airplane windows? It's there for a very important reason. Almost every airplane window has a tiny hole near the bottom called a bleed hole. When a plane flies at high altitude, the air pressure outside becomes much lower than the pressure inside the cabin. Without this tiny hole, the pressure difference could put too much stress on the window. The bleed hole helps regulate pressure between [music] the window layers, making flights much safer. It also prevents the windows from fogging up. So that tiny hole isn't a defect, it's actually one of the reasons airplane windows stay safe during flight.
