Brand OOOToyz Weight 0.1kg Color As shown Materials Multimaterial Suitable Age 7-14 years old The principle of the experiment is based on the immiscibility of oil and water, as well as the solubility of pigments in water. In the experiment, colored pigments are dissolved in water, and then drops of oil are added. Due to the immiscibility of oil and water, the oil droplets form separate spheres that float on the water surface. As the pigments are soluble in water, they penetrate into the oil droplets, giving them different colors. Since the oil droplets are independent, different colored droplets can mix together to create various color combinations. This experiment demonstrates the immiscibility of oil and water and the principle of color mixing.
