How to Make a Rainbow and Why They Form

SciShow Kids

This engaging video from SciShow Kids guides young students through the science of rainbows, combining a hands-on experiment with clear conceptual explanations. Host Jessi demonstrates how to create a personal rainbow indoors using simple household items—a glass of water, paper, and sunlight—before diving into the physics behind the phenomenon. The video transitions from this concrete activity to abstract concepts, using animations to visualize how white light is composed of multiple colors that separate when passing through water.
