What is color? Why do we see different colors? Demonstrate and explain to students why objects look the color they do using these three highly visible color wheels and a centrifuge device! A two-colored wheel is placed on the centrifuge device and spun. As the wheel spins, one single color is seen. Different colors are seen as each of the color wheels are spun. Kit includes three wheels and a detailed instruction guide. A great demonstration to introduce the topics of reflection of light, primary colors and persistence of vision. Bracken’s Demonstration Spinner (AP6202) is required and sold separately.
