Tips for Best Results in the Classroom:
1. **Find a Darkened Room:** Block out competing ambient light by pulling down window blinds.
2. **Isolate a Light Beam:** Use a bright, directional LED flashlight, laser pointer, or allow a single beam of direct sunlight to pass through a small slit in a window cover.
3. **Adjust the Angle:** Slowly rotate the prism in the path of the light beam. Watch as a sharp, vibrant rainbow casts perfectly onto a white wall, poster board, or ceiling!
