I'm not trying to steer attention away from the testosterone fueled display of cynicism goin on in here, but I think I may have done this one or two times in my day. To my relief, the volcano is designed in such a way that you can't blow the bag out, the valve that lets in the vapor remains open as long as it is connected to the chamber, so the vapor will expell from there. Nothing bad happens except a wasted hit or two.
