Airbags

It's A How do airbags work? They don't work. They chill and relax Nah. Airbags save our lives during an accident with the help of a decomposition reaction. What? Yes. During an accident or collision, it just takes about 50 milliseconds for us to So, there is very less time wit Hence, when there is a collision, the sensors called accelerometers detect it and send electrical signal to an igniter. The igniter ignites a chemical propellant called sodi Producing sodi Now, since t Helping save our lives. Why are airplane windows oval? Because I told the airplane manufacturers to do so. Oh, stop bluffing. When airplanes fly at Hence, the cabin slightly expands, thus creating stress w Now, when the windows were square or rectangular, the stress caused tension to build up at the corners of square windows. T So sad. Hence, t Oval windows provide a smoother path for stress to flow due to why do our fingers get wrinkly? Because they want to look No. A popular research suggests that wrinkly fingers are a reaction of our nervous system. When our fingers are in water for a long time, our nervous system causes the blood vessels present in the deeper layers of our skin to constrict. T But as the topmost layer does not shrink, it becomes loose, thus forming small folds or wrinkles. But why does t Scientists suggest that t Wrinkly fingers help in getting a better grip to pick up wet objects. Preventing them from slipping from our hands. Even our feet get wrinkly, helping us to walk in water without slipping. Can pure oxygen kill you? No idea. The air we breathe has many gases out of when we inhale, much of the oxygen present in air binds to the hemoglobin in red blood cell. And is transported to various cells where it helps to produce energy. However, some inhaled oxygen also turns into free radicals. Free radicals are Hence, our body produces antioxidants that neutralize the free radicals. But if we inhale pure oxygen for a long time, then the n It becomes difficult for the antioxidants to neutralize that. Hence, these unstable free radicals begin to bind with proteins in red blood cells and change their chemical structure. As a result, our immune system doesn't recognize the red blood cells and begins to kill them. Besides t
