Eggs float in salt water because salt water has a higher density than fresh water. Density is defined as the amount of matter, in this case salt, in a given amount or medium. The more matter, the denser it is.Know More
The salt water egg experiment is one of the easiest ways to demonstrate how density works. The components of this experiment are two raw eggs, table salt, two containers deep enough for an egg and tap water.
First, each container should be filled almost to the top with tap water. Add 6 tablespoons of salt in one container stir until completely dissolved, and then place one egg in each container. The egg in the salt water will sink while the one in the container with only tap water will float.
In this experiment, the egg sinks in plain water because the egg is denser than the water. It pushes the water particles out of the way and sinks to the bottom of the container. In the other container, the salt ions and the water ions have bonded together, which makes the water more dense than the egg. These new particles essentially hold the egg up in the water, causing it to float.Learn more about Dairy & Eggs
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.Full Answer >

To boil eggs with baking soda, determine which of your eggs are oldest by watching their motion in water, add a teaspoon of baking soda to the cooking water, and place the oldest eggs in the pot of water. Adding baking soda makes it easier to peel the eggs after they have been cooked.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 >
