If you’ve ever been in a car accident, you know what an airbag is. But how do they work? In this BrainPOP UK movie Tim and Moby explain how airbags are able to absorb the force of your body as it’s thrown forward during a crash, and how they protect you from hitting the windshield. In this educational, animated movie you’ll learn how quickly airbags deploy, how they use sensors, igniters and gas propellant to inflate so quickly. And remember the importance of always wearing a seatbelt — even in a car with an airbag. So buckle up, and enjoy the movie!
