How can I tell if an unopened egg is raw or cooked? Spin the egg on its side on a flat surface. If your egg rotates smoothly, with effortless grace, it is hard-cooked. If your egg wobbles noticeably, it is uncooked. The wobbling occurs because centrifugal force continuously changes the raw yolk's position inside the egg and so keeps altering the egg's center of gravity. How to tell if an egg is fresh:

Place the suspect egg in at least several inches of water in a bowl or pot. If your egg sinks and lies on its's side, you have a fresh egg. If it sinks but stands partially or fully erect on its tapered end, your egg is over the hill, though technically still edible. If it floats, you are looking at a rotten egg, more suitable for a garbage heap than a stomach. An egg acquires buoyancy as it ages because, while it's yolk and albumen (egg white) are gradually losing moisture to the outside world through the porous shell, the size of it's air pocket is increasing. Why should eggs be stored upright? Upright, in egg storing terminology, means with the larger end up (tapered end down. Upright storage helps retard spoilage because it maximizes the distance between the yolk and the egg's natural air pocket. That gaseous space is potentially the egg's most prolific breeding environment for airborne pathogenic bacteria, and the yolk is more perishable than the albumen (egg white). It stands to reason, therefore, that you must keep the yolk as far away as possible from the air pocket. When the large end is down the air pocket arches upward (as doesn't any air bubble rising through a liquid). From: Kitchen Science Shared By: Pat Stockett Submitted By SHARON STEVENS On 10-18-94
