Check an egg's age in a glass of water
Eggs pick up air as they age. A glass of water shows you how old one is without cracking it.
- Fill a glass or bowl with cold water.
- Gently lower the egg in.
- If it sinks, it's fresh. If it floats, it's older: its air pocket has grown as moisture escaped through the shell.
Tip: The test mostly measures age, not whether the egg is safe. Storage and shell thickness change how fast eggs age.
Try it now: Test the oldest egg in your fridge against the newest. Which sits higher? [the older one]
