Crushing the car– is that triggering the airbag?

Hello, the inner child in me always wanted to smash an old car with a hammer. Now I would have the opportunity, because an acquaintance has an old car close to the scrap value and would make it available to me. The question is: Could the airbags be triggered when knocking around on the body? I am clear that if the battery + waiting time is disconnected, the trigger electronics will no longer respond, because the necessary voltage for the trigger signal is missing. I don’t want the airbag to open suddenly without warning. Can you make it safe, pounding around with an airbag on the car with an airbag, but without a battery? Or is it only safe if the airbags have been removed / ignited? Best regards Xeneon1
