On board the space shuttle, dehydrated foods and drinks make up much of the menu. The major reason for using dehydrated foods and drinks is that water, a byproduct of the shuttle's fuel cells, is abundantly available for food preparation. Using rehydratable food and drinks significantly reduces weight. In this activity, students will dehydrate food and use a formula to calculate the percentage of moisture loss.
