Consuming excessive amounts of aluminum has been linked to a variety of health problems, including Alzheimer's disease. Michael was curious about whether this metal leaches out of the aluminum foil used to store various foods. He hypothesized that the more acidic the food or beverage stored, the more aluminum would leach out.
Michael placed balled-up squares of aluminum foil in samples of several liquids, including lemon juice, vinegar, distilled water, and Coca-Cola. After allowing the foil to soak overnight, he tested the aluminum contents of the liquids. He found that Coca-Cola and vinegar absorbed the most aluminum, followed by water and lemon juice.
