Last year I found an old air bag in the garage from a Saab I had scrapped, it was over 20 years old so I thought I would see what would happen.
I placed it in the middle of my garden with some long wires to the connector. I was about 30 foot away and put the wires on a battery. SWMBO was not pleased at the noise and secondly I had an area of grass that was destroyed.
