Float my egg?

People drop eggs in water to see if they float or sink and if it sinks its fresh but if it floats its old and is thrown away. But, my partner and I are doing an experiment we like to call “Float my egg?” This experiment tests if an egg will float in water when salt and if so, how much table spoons of salt will it take to make the egg float? The materials needed for this project would be 3 cups, water, salt, tablespoon, and 3 eggs. The concepts to this experiment is to collect 3 clear cups and fill them up with water, next we would set an egg in one of the cups of water, then add tablespoons of salt to the water. Whale we are doing our experiment we would keep track of what’s going on with the egg and do this concept with the other eggs to.
Why does an egg float in water when salt is added? The reason why the egg would float in water when salt is added is because when an object’s density is greater than the water’s density the object will float. If we just dropped an egg in fresh water the egg would obviously sink. So by adding salt to water it increases the density of the water, which causes the object to float.
Some theories of this experiment in the past would be that the egg will float when about 5 tablespoons of salt are added to the glass of water. Another theory from past experience is to add 6 tablespoons of salt to the glass, but both experiments say not to stir the salt into water so that it does not dissolve. Some say that it matters what type of salt you use. This is not true you can use any type of salt and you will still get the same results.
Density=mass/volume (Density equals mass over volume) is the formula that helps describe this experiment. This formula explains in mathematical terms that density is equal to the amount of matter in an object in a certain volume.
