Now, you might be thinking, how does this magic work? It's actually pretty cool. The eggshell is semi-permeable, allowing water to pass through while keeping bacteria and other microorganisms out. When an egg is placed in contaminated water, the bacteria and pollutants stick to the eggshell, causing it to float.
This test is not only fun to try at home, but it's also a valuable tool for communities around the world to monitor their water quality. By using this simple and cost-effective method, people can ensure their water is safe to drink and take action to protect their health.
