Nursery students conducted an experiment entitled Rainbow Milk. They used milk, food coloring, cotton buds, and dish detergent to observe the new colors that appeared when they dipped cotton buds coated in dish detergent into droplets of food coloring. Apart from getting to know the secondary colors, by this experiment they also observe how the chemical properties of water, fat, dish detergent, and food coloring interact in a swirl of color in an interesting way. ***
