The Magic Milk science experiment is a colourful and captivating STEM activity that introduces children to the fascinating science of surface tension. By adding drops of food colouring to milk and touching the surface with a cotton swab dipped in washing-up liquid, children can watch vibrant colours swirl and dance across the milk. This eye-catching reaction demonstrates how soap breaks the milk’s surface tension and interacts with the fat molecules, creating a beautiful display of moving colours.
Perfect for classrooms, homeschool lessons, science fairs, and at-home learning, the Magic Milk experiment encourages children to make predictions, observe changes, and record their discoveries like real scientists. It helps students explore scientific concepts such as surface tension, molecular interactions, and chemical properties while developing observation, inquiry, and critical-thinking skills. Easy to perform with common household ingredients, this exciting STEM activity combines science and creativity, making learning both fun and memorable.
