@thefuture.explanation: A car airbag is a split-second safety system designed to reduce injury during a collision. When sensors detect sudden deceleration, the control unit triggers a chemical reaction that generates nitrogen gas, inflating the airbag in roughly 30–40 milliseconds. The bag then vents gradually, absorbing impact energy before the occupant reaches hard surfaces. Paired with seat belts, airbags dramatically lower the risk of serious injury by managing forces the human body cannot withstand alone. Why it matters: This is one of the fastest mechanical decisions happening around us, quietly saving lives millions of times every year.
