If you’ve ever been in a car accident, you know what an airbag is. But how do they work? In this BrainPOP movie on airbags, 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 it protects you from hitting the windshield. You’ll learn about the lightning-quick speed at which airbags deploy, how they use igniters and gas propellant to inflate so quickly, and the importance of always wearing a seatbelt — even in a car with an airbag. So buckle up, and enjoy the movie!
