The Floating Egg

Experiments | 8-11 yrs | Video

REQUIREMENTS:-

  • 2 glasses
  • Water
  • Salt
  • 2 eggs

WHAT TO DO:-

Place the glasses together and fill them up half way. Now add one egg into one of the glasses. In the other glass, add 3-4 tea-spoons full of salt and stir well. Place the second egg into this solution.

WHAT HAPPENS:-

When an egg was placed in the undiluted solution of water, you would have noticed that the egg sank to the bottom of the glass. On the other hand, the egg that was added to the saltwater solution came up to the top and remained afloat.

WHY THIS HAPPENS:-

The egg sinks in the first glass because the density of the egg was more than the density of fresh water. However, after adding salt to the solution, the density of water increased and was more than the density of the egg, thus enabling it to float.
