Coca cola experiments for children

Surely on more than one occasion, we have seen one of the many viral videos found on social networks, in which soft drinks are used to carry out crazy experiments.

It is quite normal that when watching these videos, many of us wonder why what we are seeing is happening and how we could manage to do it ourselves.

That is why this time we wanted to give you a brief explanation, so you can learn to do home experiments using one of the most famous soft drinks in the world, Coca Cola .

These types of experiments are ideal for entertaining the smallest of the house and at the same time, introduce them to the wonderful world of scientific experimentation.

Easy experiments with coke

Some experiments are much easier than others, but since in this case we want to do it with children, we will show you a fairly simple one.


  • 1 Coca Cola medium plastic
  • 1 party balloon
  • 1 funnel
  • ½ glass of salt

How to do the experiment?

Before starting, it is necessary that this be done with adult supervision and preferably in open spaces.

First, we insert the tip of the funnel into the balloon so we can add the salt.

Then we open the mouth of the balloon and attach it to the mouth of the Coke container.

Finally we raise the balloon so that the salt falls into the bottle and we observe the reaction that occurs.

This reaction is known as “nucleation”

When we introduce the salt, it allows the water molecules to separate from the carbon dioxide found in this type of beverage, and already separated;it comes out of the bottle in the form of gas.

Scientific experiments with coca cola

To get into a more scientific wave, we want to show you an experiment that, like the vast majority of serious scientific experiments, lasts a long time. This time we will have to wait a year to see the results.


  • 1 boiled egg
  • 1 Coke
  • 1 small container

How to do the experiment?

Let's pour the coke into the container and add a boiled egg, making sure that the drink completely covers the egg.

After having been patient and waiting for a year to pass, we will remove the egg from the container and we will see how its shell will have completely disappeared.

This change occurs because Coca Cola, like the rest of soft drinks, contains an ingredient called phosphoric acid, which ends up acting on the minerals that make up the egg shell, especially of calcium carbonate.

This experiment is ideal for understanding the damaging effect that these types of drinks have on our tooth enamel and on our bones. Remember that these are also made up of calcium, in the case of our teeth, this is found in calcium phosphate.

This is one of the reasons why soft drinks deteriorate teeth and increase the probability of cavities, in addition to the fact that they have a high sugar content
