Survival Doc demonstrates that carbon dioxide is heavier than ordinary air. Carbon dioxide can be used to displace air and oxygen in containers for long term storage of food and other survival supplies. Removal of oxygen prolongs storage life and reduces rust and corrosion of metal objects like guns and ammo. Dry ice, which is solid carbon dioxide, can be used as an economical and practical source of carbon dioxide. Oxygen can also be removed from storage containers using oxygen absorbing packs.
