Why does cookies retain their crispness only when kept in air-tight containers?

The air in the environment contains moisture, which the crackers would absorb if they were not kept in an airtight tin. Keeping them in a tin prevents them from being exposed to a lot of moisture (there's still a little in the tin, but not nearly as much as their would be if the crackers were kept out in the open), hence they retain their crispness.

∙ 13y agoBecause the air contains some moisture anything left out will gain or lose moisture to equalise with air around it. Therefore crisp foods will slowly absorb moisture and become soft unless kept airtight. Conversley foods with higher moisture contents than the air will lose their moisture which is why bread, cheese, cakes etc dry out. The dryer the air the slower your cookies will soften

∙ 14y agoSome cookies will absorb moisture from the air - probably due in part to their sugar content - which will make them less crisp. By storing them in an air-tight container, the exposure to moisture is limited.
