almost blew a bottle
Basically, the blow down tube just directs the N20 outside of the car, when the safety disk pops. The safety disk is the part that keeps it from exploding.
Yeah, I'm wondering that now...the disc is basically just a thin piece of aluminum that is flat. Once you put the disc in and fill the bottle the disc gets a divot in it from the pressure. I'd imagine the disc would go before anything else considering the thickness of the aluminum disc and the thickness of the bottle.
