What is the data for egg flotation?

Egg flotation is a method used to assess the viability and freshness of eggs, often based on their buoyancy in water. Fresh eggs typically sink and lay flat on the bottom, while older eggs tend to stand upright or float due to the increasing size of the air cell as moisture and air permeate the shell. The floatation test is often used in both culinary contexts and in veterinary practices to determine the freshness of eggs. Generally, eggs that float are considered no longer safe for consumption.
