[QUOTE="7.62marksman, post: 373195, member: 8005"] what about dry ice would that last longer might be a stupid question but i had to ask i found this Carbon dioxide is quite safe and will not kill you if you breathe it. What will kill you is the absence of oxygen: we need to breathe oxygen, because it is necessary to burn the fuel that powers our heart and body, if we breathe only other gases, even if they are harmless, we can die because of absence of oxygen.
