The Bouncing Egg Experiment
There is nothing quite like hands on science experiments for kids to really learn about scientific discovery. This Bouncing Egg Experiment is an experiment that children can prepare and do independently. Young scientists will have the ability to compare and contrast the effects that vinegar has on the properties of three eggs that are exposed to the substance for three varying time frames.
How It Is Done
Vinegar is an acid and the eggshell is made up of calcium carbonate. By soaking the egg in vinegar the vinegar permeates the eggshell through the process of osmosis. During this process, the egg shell structure breaks down and dissolves. The calcium will react to become carbon dioxide gas which is released into the air leaving behind the egg's pliable unbroken membrane.
