Why do Airplane Windows have Tiny Holes? + more videos | #aumsum #kids #science #education #whatif

It's AumSum Time. Why do Airplane windows have tiny holes? Oh No. Is this airplane about to break up? Oh AumSum. When an airplane starts climbing upwards, the air pressure starts dropping. But, in order to keep the passenger safe, airplanes maintain the internal air pressure. Thus, there exists a huge air pressure difference. Now, air from high pressure area starts moving to low pressure area. Putting a lot of stress on the airplane windows. Airplane windows are made up of outer, middle and inner panes. The inner pane simply protects the other panes. The middle pane actually consists of tiny holes. Also, there exists an air gap between the middle pane and the outer pane. Now, these tiny holes help in balancing the air pressure. Between the passenger cabin and the air gap. Hence, thanks to the tiny holes. The outer panes face the brunt of cabin pressure in a gradual manner during the flight. The tiny holes also help in releasing moisture from the air gap. Thus preventing frosting of the windows. Why does hot air balloon float? Because it has invisible wings. No. It is because of density. Density is the measure of mass present per unit volume. Lesser the density, lighter will be the object. Now, density varies with temperature. Oh dude. It is so complicated. Alright. I will explain. When a hot air balloon is on ground. The air inside and outside the balloon is of same temperature and density. However, when we turn on the burner of the balloon. The air inside the balloon starts getting hot. The molecules of air move faster and spread apart, taking up more space. Hence, the air inside the balloon becomes less dense than the air outside. As less dense air is lighter, the hot air balloon rises and thus, begins to float. Why does airplane food taste bad? I don't know. Wait, I will explain. Our ability to perceive taste is affected by a few factors such as humidity, air pressure, etc. In an airplane, the humidity is less as compared to that on the ground. This makes the air in the airplane quite dry. Also, to maintain the air pressure inside and outside the airplane, the air pressure inside it is decreased. Decreased air pressure and dry air, dries our nose and mouth. Dry nose cannot properly smell odors. Yeah dude, I am not able to smell the burger. Now, smell of food helps us to understand the flavor and ingredients of the food. Thus, the food which we cannot smell properly appears unappealing. Also, dry mouth reduces the sensitivity of our taste buds. As a result, we cannot perceive the taste of food properly.
