You can tell if an egg is still good using several simple tests:

1. The Water (Float) Test

• Fill a bowl or glass with cold water.
• Gently place the egg in the water.
• If the egg sinks and lies flat on its side, it is very fresh and safe to eat.
• If it sinks but stands upright on one end, it is still safe to eat but not as fresh.
• If the egg floats to the surface, it is too old and should be discarded

This works because eggshells are porous, and over time air enters the egg, increasing its buoyancy

2. The Sniff Test

• Crack the egg open and smell it.
• A fresh egg has little to no odor.
• A bad egg emits a strong sulfur or rotten smell and should be discarded immediately

3. Visual and Texture Inspection After Cracking

• Crack the egg onto a flat plate.
• A fresh egg has a bright, rounded yolk and thick, slightly opaque egg white that doesn’t spread much.
• Older eggs have flatter yolks and runnier, more watery egg whites that spread out more.
• Any discoloration like pink, iridescent, black, or brown spots (except harmless blood spots) indicates spoilage

4. Shake Test (Optional)

• Hold the egg close to your ear and shake gently.
• If you hear sloshing, the egg is likely old because the yolk has become watery

Summary

The easiest and most reliable method is the water float test combined with cracking and smelling the egg. If the egg sinks and smells normal, it is good to use. If it floats or smells bad, discard it

. This approach ensures safety and helps you avoid using spoiled eggs.
