Explore the inner workings of a developing (non-fertilized) egg by removing the shell.
250 mL vinegar
The Science Behind the Reaction
Eggshells are made of a compound called Calcium Carbonate (CaCO3) and are dissolved by strong acids, like vinegar. Once the shell is removed, you are able to see the membrane which passes nutrients to the chick in the egg.
Take the egg in a dark room and shine a bright flashlight at it to clearly see the inside of the egg.
