How Aluminum Foil is Made?

Aluminum foil is made by squishing and stretching a big piece of aluminum until it becomes thin and bendy like paper.

Imagine you have a huge block of clay, that’s kind of what the starting material looks like, but instead of clay, it's aluminum. This block is heated up so it becomes softer, almost like warm butter.

Then, the soft aluminum goes through a machine that presses it down really hard, this is called rolling. It’s like when you press a ball of playdough between your hands to make it flat. But instead of just pressing once, the aluminum goes through many layers of rollers, each time getting thinner and thinner.

After rolling, the foil might be stretched out even more to make it really thin, almost as light as a feather! Now you have aluminum foil, ready to wrap sandwiches or keep food fresh in the fridge.
