Float an egg in water

Place an egg in a glass of fresh water. Notice what happens. Add salt to the water, stir gently, and observe what happens.
Put a tack in the eraser end of a pencil and place the pencil in a glass of fresh water. Add salt, stir gently, and notice what happens. You will see that: In the fresh water the egg and the pencil sink. As you add salt, they float higher and higher.

Explanation: A denser liquid has a greater upward lift or buoyancy. Salt makes water denser. Now you know why ships ride higher in ocean water than in fresh water, and why you find it easier to swim in the ocean than in a lake
