Mind Blowing Science: Floating Egg

This experiment, from Janice Van Cleave's Chemistry for Every Kid, is called "Magic Solution."

You need 2 clear plastic containers, salt, 2 eggs, 1/4 teaspoon of milk, and water.

Put water in both containers. Add the milk to one of the containers. This is just to make the water cloudy.
 Add salt to the second container.
 Stir. The salt water will have the same cloudy appearance as the milk water.
 Put an egg into each container.
The egg in the milk water will sink. But the egg in the salt water will float. (If your salt water egg does not float, add more salt.)
"The egg floats because it is not as heavy as the salty water. The heavy salt water is able to hold the egg up. The egg in the milky water is heavier than the water, thus it sinks."
