Effects Of Brine





-Fine Salt

-A Large Glass

-An Egg

-A Spoon

-Water

1. Pour water into the cup until it fills up half of it and then slowly put the egg in with a spoon.

Egg goes to the bottom of the cup.

2. Take the egg out of water and put in it ten tablespoons of salt, mix them with water and get brine.  Then, insert the egg again.

The egg floats.

3.Take the egg out of water and pour water until the glass is filled. Place the egg into the cup. The egg remains in the middle of the glass.

The egg is denser than water so it sinks, but salt water is denser than fresh water and therefore enables the egg to float. In the last experiment, fresh water floats above the salt water because it has a lower density; egg cup remains half being denser than fresh water and less dense than salt water.
