How Does it Work?
The egg in vinegar experiment works through the principle of osmosis. Osmosis is the movement of water from an area with high concentration to one with low concentration through a semipermeable membrane, such as an eggshell. In this instance, vinegar breaks down that semipermeable membrane and allows water from the vinegar solution into the egg.
Water seeping into an egg causes it to expand, making it larger in size due to permeability – water can now pass through it. Acidic vinegar also reacts with calcium carbonate present in the shell, breaking it down and releasing carbon dioxide gas.
Finally, the egg becomes so swollen that its membrane can no longer contain the liquid inside. As a result, it becomes rubbery and bouncy! What an exciting way to demonstrate osmosis and chemical reactions!
