Did you know that if you put an egg in a cup of tap water, it will sink to the bottom? But, if you add enough salt, the egg will float back up to the surface! Why? Because the density of the egg is higher than ... With enough added salt, the saltwater solution density is higher than the egg's, and the egg will then float.

Notice that the egg will float in the saltwater but sinks in the ordinary tap water. That is because the saltwater is denser than the regular water. ... The average person will sink in ordinary water but can float like a boat in saltwater. The Dead Sea is 33% salt by mass.

I believe that an egg will float in saltwater but not in freshwater. ... First, fill one container with freshwater and then place an egg in the container to see if it will float or sink. Next, fill the second container with water and add salt 1 Tablespoon at a time until an egg floats when you place it in the saltwater.

The exact density varies depending on several factors, including its age – an older egg may contain gas that will make it float. An egg that is only slightly heavier than water will sink in pure water but might float in salt water, which is denser because it contains dissolved minerals.

The reason the egg acts differently in saltwater is because of density (the weight of the liquid divided by the amount of space it occupies). The egg has a greater density than freshwater, so it sinks. When salt is added to the water, its density becomes greater than that of ... This means that the egg will begin to float...
