We set of an airbag deliberatly which we'd strapped to a metal frame and the force of the explosion is unreal.

So if i was you don't test an airbag with a ohmeter just in case it does explode in your face becaue it has nothing to hold the airbag down so the force of the explosion will just fling the whole unit into the air and take you up with it.

I've seen video's where people sit on them and the foce actually lifts them off the ground with ease.
