• Stir in the salt
• Carefully pour in plain water until the glass is nearly full. Be careful not to disturb or mix the plain water with the salty water.
• Gently lower the egg into the water and watch the egg float into the middle.
• Why? Because the salty water in the bottom of the glass is denser than the water at the top of the glass.
