Introduction

Saline water is more dense than fresh water. Here we conduct a small experiment to show how an egg sinks in fresh water, but floats on saline water!

Tools

Parts

    • Ensure the egg shell stays intact throughout the experiment.

    • Wash Hands with soap after handling eggs.

    • Storing eggs for too long without proper refrigeration will spoil it.

  1. Collect a fresh egg. Fill the cup with fresh water from tap. Put an egg into the cup of water. Fresh egg being high in density, it should sink in the cup of water
    • Collect a fresh egg.

    • Fill the cup with fresh water from tap.

    • Put an egg into the cup of water. Fresh egg being high in density, it should sink in the cup of water

  2. Add Salt to the cup of water and stir it well. Wait for some time for the salt to dissolve. Add about 2 Tablespoon of Salt / 100 ml of water you use.

    • Add about 2 Tablespoon of Salt / 100 ml of water you use.

    • Saturated Salt solution is necessary for the egg to float.

    • Put an egg into the cup containing salt water.

    • Now, the egg should float in Salt Water. This is due to the fact that Salt Water is more dense than the egg.

    • Egg would have got spoilt due to which egg floats even without adding salt.

    • What happens if you put an old egg in the cup of water?

    • Collect a fresh egg each week for three weeks and put it in different cups of water. Compare their relative depth.
