With this experiment, food coloring creates amazing designs on the surface of milk using only dish soap. This experiment, known as magic milk, is a visual representation of some pretty complex chemistry and results in fun, exploding colors. The interaction between the molecules within the milk, food coloring, and soap creates colorful designs that are sure to pique your curiosity.

This cool experiment is appropriate for a science fair project, high school chemistry, or even a kindergarten science project - it's versatile and easy! Enjoy this fun science experiment for kids and kids at heart with supplies found in most household pantries.

▶️ How to make magic milk:
Step 1: Pour some milk into the plate until it forms a thin layer at the bottom.

Step 2: Wait 30 seconds until the milk is still on the plate.

Step 4: Carefully add a few drops of food coloring right at the surface of the milk.

Step 5: Dip a cotton swab in soap.

Step 6: Gently touch the soap-covered cotton swab to the food coloring. Observe as the colors start shooting around in the milk.

▶️ How the magic milk experiment works:
I don't exactly know what's going on inside this experiment. I know it has something to do with the charges on the molecules attracting each other in such a way to cause this macroscopic movement of the food coloring across the surface of the milk. Even the American Chemical Society gives kind of a half explanation that doesn't actually go into detail about what's happening.

The best explanation I've seen involves micelles forming around the fat particles within the milk. The outsides of these micelles are attracted to the food coloring particles and, because they're less dense than the milk itself, they travel across the surface, dragging along food coloring particles as they go. Now, what I'm not sure about is what causes them to move at such speed across the surface of the milk. So I tried to go a little deeper and find something others might have missed with super slow motion. It looks really cool, but I didn't pick up on anything that helped me understand the experiment. If you have any ideas about what might be happening, post them in the comments and let me know.
