Did you know that it is easy to turn ordinary milk into a rainbow of crazy colors? All you need is 4 items that you probably have in your kitchen already.
We enjoyed watching the colors in the milk dance and hope you do too.

Supplies Needed for the Magic Rainbow Milk Science Experiment
- Milk (Must be either Whole or 2%)
- Food Coloring. The more colors the better
- Dish Soap
- Shallow Dish or Bowl
Magic Rainbow Milk Science Experiment Instructions
Step 1 – Pour some milk into a shallow dish or bowl until the milk covers the bottom.
Step 2 – Add some drops of food coloring on the milk. You can use a variety of colors, just be sure to add 3-4 drops of each color.
Step 3 – Add a drop of dish soap into the center of the milk
Step 4 – Watch in amazement as the colors dances across the surface of the milk
How Does the Magic Rainbow Milk Science Experiment Work
The dish soap causes the fat and the water in the milk to seperate and spread apart. The result is the dancing motion of the food coloring in the milk. Whole Milk and 2% Milk contain more fat than other milk, so that is why it is important to use one of those kinds of milk for the experiment.

I hope you enjoyed the experiment as much as we did. Here’s some printable instructions.
