Many beverage cans are made from aluminum, a malleable, reactive metal. Even when great force is applied to a can, causing the body to collapse, the ends maintain their original shape. Aluminum cans are also able to withstand the acidity and carbonation of many types of beverages contained inside. Are other components besides aluminum present in an “aluminum” beverage can? This demonstration investigates the composition of these familiar cans.
