How to see colorful sunshine

Start the light source with the button, and the white light is split by the prism to form seven-color light. Projected onto a box with a white screen that can move up and down. Through the joystick, the audience can operate the white screen. When the white screen is below, the seven-color light formed by the prism shines on the white screen. When the white curtain moves up, the box is opened, and we can see the three-dimensional shape of the ballet dancer formed by the rapid rotation of the single line. Beautiful seven-color light shines on it, as if a ballet dancer were wearing colorful clothes.
