Peugeot 307 Seat side airbag manual firing with 12 volt battery

We fitted a new seat to the Peugeot 307 and needed to fire the old airbag before disposing of the seat. There's no where to take an old airbag in Australia to dispose of it properly and we didn't want to put it in the rubbish like lots of people do. It was easy. Connect an old 12 volt battery via a long length of speaker wire and fire it off.
