On a daily basis, milk is one of the most often drank beverages. Milk is high in calcium, which is essential for bone and tooth health. Milk can be used as a weight gainer in particular circumstances. Milk may also be used to make soap and facial masks. However, did you know that we can paint on milk’s surface? Do you want to learn how? Let’s get started!
Tools and Materials of Painting on Milk’s Surface
- Plate
- Food coloring (red, yellow. and green)
- Pure cow’s milk
- Cotton bud
- Dishwashing liquid soap
Instructions for Use of Painting on Milk’s Surface
- Prepare the tools and materials that will be used to painting on milk’s surface.
2. Pour the milk into the plate so you don’t see the bottom of the plate. Don’t need too much.
3. Pour 2 drops of food coloring for each color in the center of the plate that filled with milk close together.
4. Dip a cotton bud into the soap
5. Dip the cotton bud into the center of the milk slowly. No need to stir.
6. Press the cotton bud down until it touches the bottom of the plate.
7. Repeat dipping the new cotton bud into the soap and then dipping it again in the milk in a different place.
8. Pay attention to the changes that take place.
Explanation of Painting on Milk’s Surface
Milk and food coloring have different densities. Because food coloring has a lower density than milk, it floats on top of it. Soap and milk are incompatible. When soap comes into contact with milk, the soap compound (detergent) chases the fat in the milk, resulting in a “chase” between the milk and the soap. Because it is lighter, food coloring on the surface of the milk will flow with the soap molecules. The difference in density between milk and soap causes a circular or circular motion. Every time the soap is dipped into the milk, this will happen. Colors that keep moving and combining will generate a new color.
