Bouncing Egg

Experiments

What You Need:

Method:
Conclusion:

When you leave the egg in vinegar for the whole day, you will notice small bubbles forming around the egg. After some time, these bubbles grow bigger and eventually rise to the surface of the white vinegar. After some time, the egg will start to float due to the bubbles that have gathered around it. The shell of the egg then starts to decompose because of the vinegar. After a week has passed, notice that the eggshell has decomposed completely. Once you take it out, feel the texture of the egg. It will feel leathery. Now try and bounce the egg against the floor. The experiment demonstrates the process of osmosis. Osmosis is the movement of liquid from a solution of lower concentration to a more concentrated solution through a semi-permeable material or layer. A permeable material is one through which fluids or gases are able to pass. The vinegar slowly diffuses through the eggshell until it dissolves it completely, leaving the egg rubbery or leathery in texture. As the eggshell breaks down, carbon dioxide is produced which appears in the form of bubbles. Leaving the egg immersed in the vinegar will cause its shell to dissolve completely.
