Air bag messing
Discussion
Anyone ever set off an airbag out of the car before? We have an opportunity as I'm replacing one of the airbags on one of our cars and I'd like to make it educational for the kids. Obviously safety will be top of the list and there's no reason at all why this can't be done safely, that's the way we'll do it.
Is there anything better than simply setting it off on the ground. Could I stick it next to a watermelon or something like that?

Just make sure to use an appropriate sized airbag in an appropriate setting:

We won't be doing that. https://youtu.be/Fr-CNfi04IY?feature=shared&t=...
aaarrrr a speciality of mine!
Make sure its anchored down well as can easily become a missile, but in essence bend back the bridging bar in the connection or insulate what ever pins you use, then bodge a wire to each of the gas generator pins, add 12V and pop goes the airbag.
I've seen airbags bend the top of skips when chucked inside and set off face down, so used to mount them into a bench mounted vice with the bench screwed to the floor.

Didn't realise they were so powerful. Good to know so we can make sure we mount it securely and stay at a safe distance!

We used to have to set them off when replaced , couldn't send them back to the factory, had a dedicated lead, with enough slack on it to be well away, inside a cage, and bang. They do make a noise.
yes, even though you don't hear about it much it had crossed my mind that there would be parts of the automotive industry where controlled detonation of air bags is a regular part of the work due to the obvious issues surrounding handling of explosive devices. Not sure where and when... but since you mention it I am now not surprised to hear that it happens. ingenieur said:

They are designed to meet a rapidly moving, heavy object coming towards them, ie the head and upper torso of a human in an accident with enough of a rapid deceleration to set them off. 
Like those idiots in the video, if one object is stationary, there is a LOT of force. Good luck! 
Bought a leather interior on Gumtree from a BMW to make mancave seats. Welded up frames for the front seats and bolted them on, very comfy but one of the seats at wrong angle and electrically adjustable. Got a spare car battery and disconnected the wires under the seats, trial and error to see which wires controlled which motors. Stupid me didn't even stop to think there was an airbag in there as well as all the electric motors. Connected 2 wires to the battery and the side bolster air bag goes off. Nearly s@@t myself, fortunately I was at the front of the seat and not the side or it could have done serious damage. Now have to sew up the stitches again on the side

Love that. Would have been so easy to do and so obvious what went wrong once it had been done! ingenieur said:

Suggests you don't know what you are doing and for the sake of your children you should not "play" with a live airbag
