Is An Egg Bad If It Sinks

An egg's freshness can be determined by placing it in a glass of water. If the egg sinks to the bottom and lays flat on its side, it is fresh. If the egg sinks but stands upright on its smaller end, it is still good but not as fresh. If the egg floats, it is no longer fresh and should not be eaten.

The reason for this is that as an egg ages, the air cell inside the egg gets larger. This is because the egg's shell is porous, and air can pass through it. As the egg ages, the water inside the egg evaporates, and the air cell gets larger. This causes the egg to become less dense, and it will float in water.

So, if you have an egg that you're not sure about, you can put it in a glass of water to test its freshness. If the egg sinks to the bottom and lays flat on its side, it is fresh and good to eat. If the egg sinks but stands upright on its smaller end, it is still good but not as fresh. If the egg floats, it is no longer fresh and should not be eaten.

Here are some additional tips for testing the freshness of an egg:

The shake test: Gently shake the egg. If you hear a sloshing sound, the egg is not fresh.
The smell test: Crack the egg open into a bowl. If the egg smells bad, it is not fresh.
The visual inspection: Look at the egg's yolk and white. The yolk should be firm and round, and the white should be clear and firm. If the yolk is runny or the white is cloudy, the egg is not fresh.

If you are unsure whether an egg is fresh or not, it is best to err on the side of caution and not eat it. Eating a bad egg can cause food poisoning, which can lead to nausea, vomiting, and diarrhea.
