This simple test helps you determine the freshness of an egg by checking its buoyancy in water. Fresh eggs sink and lie flat, while older eggs may stand upright or float. Ingredients: 1 fresh egg. 1 bowl of water. Instructions: Fill a bowl with water. Carefully place the egg in the water bowl. Observe the egg's behavior in the water. If the egg sinks and lies flat on the bottom, it is very fresh and safe to eat. If the egg stands upright on the bottom but doesn't float to the top, it is still good to eat but not as fresh. If the egg floats to the top, it is no longer fresh and should be discarded. Prep Time: 2 minutes Cook Time: 0 minutes
