An Experiment With An Egg and Soda a lesson in dental health

For this experiment you’ll need:
a white egg
a dark colored soda
a glass
an old toothbrush
***if desired you can choose other beverages to try
This experiment is so easy peasy.  All you need to do is put a white egg in each glass that you have and pour the beverage  in to cover the egg.

In our glasses we chose to use apple juice and a dark colored cola.  I asked C what she thought would happen to the eggs.  She thought maybe they would change colors.  We mostly drink apple juice in our household so C wasn’t even sure if she wanted anything to do with the cola.

After a couple hours the cola made the white egg light brown…..that fast!

The apple juice made the white egg a light brown too.

A day later the eggs were quite dark so I explained to C how the eggs got stained.  I asked her, “What would happen to your teeth after drinking apple juice if you never brushed your teeth?” My daughter concluded that her teeth would get brown like the eggs.  So I had C take an old toothbrush to see if she could get the eggs clean.

The apple juice came off in brown little chunks.  The dark colored soda had to be really scrubbed. Both were not easy to clean.

Here is the cola submerged egg half cleaned. It makes you really think how important it is to brush your teeth after seeing this.  How would the eggs look after more time? Probably worse.

This experiment is a good lesson in dental health.

On You Tube there is an experiment with a dark colored soda in which they left the egg for one year…365 days. Take a look at the video here and you may think twice about drinking colas or at least it will encourage you to brush your teeth.  The shell of an egg contains calcium, sodium, and phosphorus….and after 365 days the shell disintegrated.
