Whether on the race track or on the street, we've all seen it: minor crashes that caused a surprising amount of injury, and big, nasty crashes that let the driver walk away--or at least survive. Why does that happen? It comes down to the way the body responds to the forces in a crash.
In this video, the Insurance Institute for Highway Safety (IIHS) shows us what exactly happens to the body during a series of typical car crashes. The results are drawn from their own testing and from real-world racing crash data.
Don't worry about the classroom-like atmosphere of the video--you will learn something over the next 24 minutes, but you won't mind it a bit. Through a series of animations, models, and experiments, you'll see how your brain can bounce around inside your skull, how your heart can move around in your chest, and how much force it takes to liquify your organs and break your bones.
