A rainbow is weather putting on a science demonstration. Sunlight enters a raindrop, bends, reflects, and leaves in a fan of colors — a tidy explanation for something that still makes children run to the window. Books get to keep both halves of that experience: the real optics of white light and water, and the old imaginative question of what might happen if the bright arc stayed, disappeared, or could be carried home.
Bookroo’s collection of rainbow books ranges from ribbon-filled board books and color stories to classroom experiments with prisms, mirrors, and glasses of water. Our editors chose twelve favorites that make the science visible, use the spectrum inventively, and hold up to repeat reading.
