Science Experiment: A Floating Egg?

I took an egg out of the fridge and waited for it to get at room temperature, then I took out to container of salt, a teaspoon, a spoon to stir with, and a glass filled with water.

I dropped the egg in the cup and it sunk straight to the bottom of the glass.

Then I took the salt container and poured some salt into the teaspoon. I poured the salt into the glass .

I stirred the salt in the glass and waited for it to dissolve.

Here is were I dropped the egg into the glass after it the salt dissolved, the egg floated for a little bit then sunk to the bottom, this was after I added the first teaspoon of salt.
My Science book had told me to repeat this until the egg floated to the top, it took four more teaspoons of salt for the egg to float to the top of the glass.

The goal of this experiment was to see if salt changed the density of items. It was a fun experiment and I'm glad it turned out well.
