Egg Float Test: Myths, Procedure, Chart, Hypothesis vs. Reality
Reality: The egg float test only measures freshness, not quality. Freshness is how long an egg has been stored, whereas quality includes taste, texture, and nutrients. Myth 2: Floating eggs are bad. Reality: Floating eggs are less fresh than sinking ones, but they're still edible.

Egg Flotation Project..why Does The Egg Float In Salt Water?
Answer. Answer (1 of 11): An egg floats in salt water because salt water is more dense than water straight from the tap. The greater buoyancy allows the egg to float in the salt water, provided it is salty enough. In order for something to float, the buoyant force has to greater than or equal to the weight of the object.

The classic flotation techniques can be divided into two main types; 1) counting chamber or …
