Magic Milk science experiment for kids

Turn your Home Into a Science Lab!

Even if you are not keen about chemistry, there are plenty of table tricks science experiments that can easily be conducted in your home. One of the best ones is the magic milk science experiment. While the magic milk science experiment is simple and easy to conduct, the fun-factor is really high.

This milk and dish soap experiment’s interesting nature makes it a special one that students love to repeat more than once. Moreover, it is also a great way to learn chemistry. For those who haven’t experienced the real fun of chemical experiments before, this is a magical way to start. It is absolutely safe to conduct the magic milk science experiment in a home environment.

Note, there are a variety of educational experiments available in MySparklebox. The whole range of products is designed to make science more fun and exciting for the students.

This magic milk science experiment can be incorporated into the lesson plan of all age groups, depending on their knowledge base. It could be a great choice for the students in K1 and K2 classes.

So, let us take a look at how to proceed with the experiment.

The Colour Changing Magic Milk Science Experiment

Materials Required

Here are the items that you will need to conduct the experiment :

Magic Milk Science Experiment
  • A shallow dish or a plate
  • A cup of milk, preferably with high-fat content
  • 1 drop of dishwashing liquid
  • A few shades of food colouring (red, green, blue, and yellow)

Steps to Follow

Once you have all the items, mentioned below are the steps you need to follow.

Step 1-  Pour some of the milk into the dish. Make sure that you pour enough milk to cover the entire bottom of the plate.

Step 2-  Add drops of colour into the milk. To make things more interesting, you can add a bit of glitter too.

Step 3-  Add one drop of dishwashing liquid into the milk.

Once the liquid is added, you can simply watch the play of the colours in the milk. You do not need to stir the milk in any way. The colours will start moving away from the dishwashing liquid and will start mixing on their own. As the chemical reactions proceed, the colours will mix and present a fascinating rainbow in this magic milk science experiment. 

Gradually, the reaction of this science experiment will slow down. You can add another small drop of dishwashing liquid to try to make the colours move around again. If you are lucky, the colour play will start again.

The Science Behind Magic Milk Experiment

So what makes this fascinating play of colours happen? It is all about chemical properties and bonds.

There are various types of molecules in milk. Apart from water, these include fat, protein, sugars, minerals and vitamins. Once the detergent is added in the milk, the surface tension of milk is reduced. This allows the food colours to move around freely.

The fat molecules in milk are non-polar in nature. But the reaction between the detergent and the fat forms soap micelles. The micelle has a polar surface that gets connected with the polar water molecule and can be carried around. This is how the fat molecules get turned and twisted around as they connect with more and more soap molecules. 

The food colouring molecules are caught up in all these movements and are pushed around through the milk. With millions of molecules moving around and trying to pair up with each other, the colours get mixed up, forming beautiful patterns in this magic milk science experiment. 

Normally, the reaction between fat and soap molecules is invisible. But the addition of colours makes the movement very clear to human eyes. Once the soap and fat get evenly mixed up, the milk and dish soap experiment will slow down. Now you can consider that a chemical equilibrium has been reached in the milk.

This is why milk with higher fat content provides better results in the experiment. You get more fat molecules to make the reaction even more vigorous. 

Different Variations of the Magic Milk Science Experiment

Once the reaction has slowed down, you can add one more drop of dishwashing liquid to check for any leftover fat molecules in the milk. If yes, you will find the process repeating itself once again. In case the magic is not repeated, you need to wash the plate and start again with some fresh milk.

You can try the milk and dish soap experiment with various types of milk. Different fat percentages will result in the different play of colours. For example, you can try the magic milk science experiment with whole and skimmed milk. 

Conclusion

The colour-changing magic milk science experiment is one of the most interesting chemical experiments that can be conducted easily. Nothing teaches the students more about chemical properties and bonds than a colourful experiment that is truly magical.
