To determine the freshness of eggs, there are many popular ways.

The fresh eggs when viewed using ovoscope content is not dark, almost transparent, and the yolk is less noticeable than the old one. In another ovoscope visible air chamber in the blunt end of the egg: during long-term storage it increases in size.
