[00:00:00]Your seatbelt doesn't save you. The airbag's sodium azide explosion does.

[00:00:05]>> [music] >> X-ray the steering column, an accelerometer, a steel inflator and a minister in a folded nylon bag, all packed into a space smaller [music] than your fist.

[00:00:15]At impact, the accelerometer fires a 1.5 amp current.

[00:00:19]The sodium azide pellets detonate, releasing 67 L of nitrogen [music] gas in 0.03 seconds.

[00:00:28]The nylon bag inflates and vents simultaneously. Gas escapes through side holes as your head contacts the cushion, absorbing impact [music] energy perfectly.

[00:00:38]Follow the orange wiring. It happens too fast to see.
