Another way to check if an egg is boiled is by doing the water test. You drop the egg into a bowl of cold water, and if it sinks to the bottom, it's not boiled. But, if it stands on its end or floats, it's ready to eat! It's like a little game - will it sink or will it float?

So, what's the logic behind this test? Well, it's actually pretty simple - when an egg is raw, it's less dense than water, so it floats. But, when it's boiled, it becomes denser, so it sinks. It's kind of like when you try to swim - if you're not buoyant, you'll sink to the bottom of the pool!
