An egg floats in saltwater if the water is denser than the egg. The salt adds density to the water, but if there is not enough salt, the egg sinks.Continue Reading
The more salt that is added to the water, the higher the egg or other less dense object floats. The density comes from the amount of molecules present in the water. Saltwater has more molecules than fresh water. Thus, varying amounts of salt can be added to water to have the egg float in different spots, such as the middle of the glass. Another factor to consider is temperature. Cool water is significantly more dense than warm water.
The rule of less dense objects floating in denser water applies to larger scenarios as well. It is easier for a person to stay afloat in the ocean than in a swimming pool. Ships can easily float because they spread their density out on the surface and because some ships have air pockets, which is much less dense than water.
This concept even applies to scuba diving. Divers must make sure that in saltier water they wear more weight so that they can move and actually sink. Some have to double their body weight to adequately dive.Learn more about Dairy & Eggs

However, if the proper technique is not used, then eggs can turn out too runny, soggy or rubbery. For a perfectly poached egg, it is advisable to use the correct steps and cooking items.Full Answer >
To test the freshness of raw eggs using water, fill a large bowl with water, place a single egg in the bowl, and observe the egg. If the egg rests on its side in the bottom of the bowl, it is fresh.Full Answer >
To make a hard-boiled egg, the American Egg Board suggests placing one or more eggs into a pot of cold water, then bringing the water to a boil. As soon as the water boils, the heat can be turned off and the eggs allowed to sit in the hot water.Full Answer >
