Add about 3-4 drops of food coloring in little circles around the plate.
I made 4 circles each with a different color of food coloring.
Dip your cotton swab in the dish soap.
Now, place the dish soap-filled swab into the milk and watch the colors start to swirl.
Notes
Use Whole Milk for Best Results: Whole milk works best for creating vibrant cosmic colors due to its higher fat content. The fat molecules in the milk interact with the dish soap, causing the colors to swirl and create mesmerizing patterns. Avoid using skim or low-fat milk, as they may not produce as vivid results.
Experiment with Food Coloring Placement: Get creative with the placement of food coloring on the paper plate. Try arranging the drops in different patterns or designs to achieve unique effects when the dish soap is added. You can create concentric circles, random splatters, or even spell out initials or shapes with the food coloring drops for added visual interest.
Controlled Swirling Technique: Dip the cotton swab into the dish soap and gently touch it to the surface of the milk where the food coloring drops are located. Avoid stirring or agitating the milk excessively, as this can cause the colors to blend too quickly and result in muddy hues. Instead, lightly touch the swab to the milk and observe the mesmerizing swirls and patterns that form as the dish soap reacts with the fat molecules in the milk.
