Milk is made up of fats that you can’t really see although it does look like one uniform liquid.

It contains water, fats and proteins.

When you add your food coloring it looks as though it just sits on top of the milk.

For this winter themed experiment we chose to only use the purple and blue color. We wanted darker colors that make it feel like winter.

Once you dip your cotton swab into the milk, you’ll see the food coloring beginning to disperse and mix together which is the fun part to watch.

As you hold the cotton swab in the milk you see the colors start to swirl, you can then dip the other end into the soap to keep doing it again. It’s really such a cool process to see!

How does the magic milk experiment work?

Want the magic milk experiment explanation? First, ask the kids what they think about the process and then go from there. Once they give their hypothesis, you can then talk about the actual experiment after that.

Notice when the food coloring is added to the dish is just sits on top. It does not mix with the milk initially. Remember that milk is made up of minerals, fats and proteins.

Once the cotton swab is added to the soap, it is dipped into the milk and the colors begin to swirl and mix together.

The soap breaks the surface tension of the milk as the fat molecules interact with the dish soap and begin to move around and swirl.

The soap seeks out the fatty molecules and as the move and interact the food coloring allows you to see this and how it moves it process a fun color reaction to watch.

As the reaction stops, you’ll the colors stop swirling, you can grab another cotton swab dipped in soap to keep start the reaction again in another part of the dish.

What milk is best for the magic milk experiment?

The best milk for this experiment has more fat, I used 2% milk but whole milk would be even better since it has more fat. You want to be sure that whatever milk you use it does have fat content in it as this is key to the experiment.

My daughter was moving the plate and then the colors inside the snowflake dispersed outside of the cookie cutter which made it look even prettier.

As usual my daughter enjoyed adding more food coloring and soap to see what happened.

Simple Magic Milk Science Experiment


  • 1 1/2 cups of milk
  • Liquid food coloring
  • Dish soap
  • Cotton swabs
  • Dinner plate or shallow dish
  • Small container


    1. Pour about one tablespoon of dish soap into a small container.
    2. Pour milk onto a plate. (It’s ok if you see bubbles.)
    3. Drip a few drops of food coloring of choice in the center of the milk. You can get creative with where you drop the drops and space them out how you wish. (Note: Food coloring may spread out slightly as pictured.)
    4. Dip a cotton swab into the dish soap.
    5. Place the cotton swab in the middle of the colors and watch what happens! You should see the colors start to spread out towards the sides of the plate and change over time. You can repeat this step a few times.
    6. Tip: Kids can take their cotton swab and “draw” or “swirl” in the colors. Eventually the colors will mix together until the milk becomes one color.    
    7. If you allow the milk to sit a while before all colors are mixed completely together, you can see the milk change in neat ways as pictured here.
    8. Watch over time how different things look!
    9. When complete, dispose of milk in the sink.
