Create colorful milk art with Princess Kay of the Milky Way
Add color to dairy in this fun experiment
What’s the most Minnesotan thing you can think of?
If it involves the State Fair, dairy, or science—you’re in for a fun time! This milk art activity is all about the science of milk and why it acts the way it does.
Learn alongside the current Princess Kay of the Milky Way and a past Princess runner-up, Yvonne, as they examine why milk fat helps transfer colors and what that means for humans who drink or eat milk products.
Try it at home
What you will need
1/2 cup of whole milk
Food coloring: red, yellow, blue
2 cotton swabs
Plate (not paper)
Step 1: Start with a plate
Grab your plate and the milk
Pour half a cup of whole milk onto the plate
Step 2: Add color
Now add one drop of each of the three colors of food coloring—red, yellow, and blue—to the milk close together in the center of your plate
Step 3: Use the swab to create swirls
Place the swab in the center of the plate with the drops
Did anything happen here? What will change if you add soap to the cotton swab?
Dip the cotton swab in soap and put it back in the middle of the milk for 10 seconds
After 10 seconds, move the swab around slowly. You should start seeing swirling colors!
