The Experiment: Spin Art and Centripetal Force In this activity, students place a paper disc on a rotating platform (like a salad spinner or a motorized motor). As the disc spins rapidly, they hold markers against the paper. The Scientific Concepts Centripetal Force: When the disc spins, the friction between the marker tip and the paper, combined with the rotation, pulls the ink outward or holds it in a circular path. Rotational Motion: Because the disc is moving at a high speed, a single point of contact with a marker creates a perfect circle. If the marker is moved slowly from the center to the edge, it creates a spiral. 🎨 The Science of Color Mixing and Persistence of Vision English Explanation When the disc spins at high speeds, the various colors applied to the paper create a unique optical phenomenon. Due to the principle of Persistence of Vision, an image remains on the human retina for less than 0.1 seconds. Because the disc is rotating so rapidly, the time interval between each color passing before our eyes is too short for the brain to distinguish them individually. Instead of seeing separate streaks, the brain "stacks" these fleeting images together. To the human eye, this creates the illusion of different colors blending into a new spectrum, much like how white light is formed by the combination of all primary colors. #STEAM #Science#Kids Elite#Summer Camp
