is it backwards?

has anyone ever seen the episode of mythbusters where they did the soda & pop rocks myth? I remember hearing that more than 3 psi could be fatal if i remember right. Maybe that was stomach pressure, not lung pressure.

That's stomach pressure Nick. If it was lung pressure everyone would be a whole lot deader. Your lungs are stronger because they have to hold air, your stomach just has acids and stuff to digest food. If your food gets pressurized to 3 psi, you're dead.

I really don't think anyone cares how much pressure in what organ can kill you. Is anyone even trying to help the starter of this thread?
