Magic Milk Painting

Science fair project - Magic Milk Painting
Watch in amazement as colors come to life and dance around like magic on the surface of milk with just a drop of soap. This colorful experiment is a delight to see!


The hypothesis is that adding soap to the milk will cause the colors to move around in interesting patterns.

Method & Materials

You will pour milk in a dish and add drops of food coloring. Then, using a cotton swab with dish soap on it, touch the center of the food coloring and watch the colors move!
You will need milk, food coloring, dish soap, a dish and cotton swabs.


The soap makes the colors move in ways you never expected! Even though the colors start out mixed together, they soon burst apart in a beautiful swirl!

Why do this project?

This science project is a fun way to learn how different molecules interact to make colors move in unexpected ways.

Also Consider

Try using different types of milk, such as skim milk or half & half, to see if the results are different. You can also try different types of soap to see how they affect the movement of colors.
