Beautiful. A small correction – most airbags use pyrotechnic inflators, not compressed air.

Sidenote about airbags: they have to be folded to fit inside their module, so as it inflates it's also unfolding. In order to make sure it unfolds properly they coat it in a lubricant that can't evaporate – either talcum powder or cornstarch depending on the vehicle.

I learned this only after I scrambled out of the car my sister put in a ditch thinking it was on fire. The best part? It was a diesel car.

Who knows, maybe the engineers consider it a feature because after an accident it sure gets people out of the car quick!
