Magic Milk Experiment

Magic Milk Experiment | Science Fair Projects | STEM Projects
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?

The magic milk experiment is a fun way to learn how different molecules interact with each other to make colors move in unexpected ways. It's a very easy and fun science experiment that uses things readily available at home, but the science behind it is complex when you consider why the colors constantly move in the milk.

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.
