First, to answer this question, you must know that something floats when it is less dense than the liquid. Normally, an egg just barely sinks in in water, by adding salt to the water, it makes the water denser and thence changes its volume. It makes the water denser than the egg, which causes it to float on the water.

weight without appreciably changing it's volume.
Thus, the density (weight divided by volume) increases.
Something sinks when it weighs more than the
amount of water that it displaces. Conversely,
it floats when it weighs *less* than the water
it displaces.
An egg just barely sinks in pure water, but when
you add salt, the water becomes more dense and
the egg floats (since it is lighter than the
displaced amount of salt water).

In less scientific terms :) :
The egg will float if there is enough salt.

∙ 14y agoBecause salt allows air into the water in which the air reaches the egg and pushes it to the top of the water.

Do salt and sugar and flour make a egg float?
no, because the egg is heavy and not light witch is causing it not to float and it will be harder to float and if an egg is boil anything can cause an egg to float
How egg float in salt water funfacts?
well an egg can float in salt water because of the mass and density of it makes it easier to float
How do you make an egg to float in vinagar?
Simply put a fresh egg in a glass and cover it completely in vinegar. The egg will float because it has a lower density than the vinegar.
How salty does the water have to be for an egg to float?
The sea has to have at least 4 tablespoons of salt in order for an egg to float.
How many teaspoons of vinegar does it take to make an egg to float?
The density of the average egg will be slightly greater than water, so it will sink. To make the egg float, make the water more dense by adding salt. For one cup of water, adding three tablespoons of salt should be about enough to make the egg float.
Will an egg float in saltwater or freshwater?

Does an egg float on saltwater?

Can an boiled egg float in saltwater?

Who discovered how and egg can float on saltwater?
Probably a chicken.
What is the purpose saltwater making an egg float?
inthink because of salt water having strong molecules and make the egg float.
Why will an egg float in saltwater other than freshwater?
cuz saltwater is more dense than freshwater
Can a boiled egg float better in salt water or fresh water?
Because the density of the egg is lower than the density of the saltwater Because the density of the egg is lower than the density of the saltwater
Why would egg float in saltwater and and not freshwater?
Salt water has a higher density. The general rule is that an object will float if it has less density than the liquid in which it is placed.
What happens when you put a raw egg in vinegar and then saltwater?
The vinegar will disintegrate the egg shell and the salt will suck out all the water and shrivel the egg.

What happens to egg yolk in salt water?
The egg would first float due to the saltwater weighing more than the egg. After a few days, it would start dissolving and eventually shrink.
